[Question]Due to the restrictions of Coronavirus, Mr. Trent, the local store owner, increased the prices of goods at his store by 15% each to make the same income he was making before. If buying an orange was $40 and the price of purchasing a mango was $50, calculate how much it costs in total now to buy ten oranges and ten mangoes at the new prices.
[Answer]If the initial price of orange was $40, after the increase, the price rose by 15 / 100 * $40 = $6. The total price of buying an orange at the new price is $6 + $40 = $46. For the mango, the price increased by 15 / 100 * $50 = 7.5. The price of purchasing a mango at the new price is $50 + $7.5 = 57.5. To buy ten oranges it would cost $46 * 10 = $460. To buy 10 mangoes, it now costs $57.5 * 10 = $575. The total cost of buying ten oranges and ten mangoes is $575 + $460 = $1035. The answer is 1035.
Q: Mike and John dined at the Taco Palace restaurant. They each ordered the Taco Grande Plate as their main meal, but Mike also ordered a side salad for $2, a plate of cheesy fries for $4, and a diet cola for $2. As a result, Mike's lunch bill was twice as large as John's bill. What was the combined total cost, in dollars, of Mike and John's lunch?
A: Let "x" be the cost in dollars of the Taco Grande Plate. Since twice the cost of John's Taco Plate equals the cost of Mike's Taco Plate plus added items, then 2x = x + 2 + 4 + 2. Simplifying the equation, we get 2x = x + 8. Subtracting x from each side of the equation, we are left with x = 8 dollars as the cost of the Taco Grande Plate. Thus the combined total cost of Mike and John's lunch is 8 + 8 + 2 + 4 + 2 = 24 dollars. The answer is 24.
Question: Jessica was trying to win a gift card to her favorite store. To win, she had to guess the total number of red & white jelly beans in the bowl of mixed color jelly beans. She figured it would take three bags of jelly beans to fill up the fishbowl. She assumed that each bag of jellybeans had a similar distribution of colors in each bag. She bought one bag of jellybeans and separated them by color. She had 24 red, 13 black, 36 green, 28 purple, 32 yellow and 18 white. What was Jessica's guess as to how many red and white jelly beans were in the fishbowl?
Answer: We know she counted 24 red jelly beans and 18 white jelly beans so 24 + 18 = 42 jelly beans. Even though she only bought 1 bag of jellybeans, she thought it would take 3 bags to fill up the bowl. So 3 bags * 42 jellybeans = 126 total red & white jellybeans. The answer is 126.
[Question]In Rodrigo's classroom in the morning there are red chairs, yellow chairs, and blue chairs. There are 4 red chairs. There are 2 times as many yellow chairs as red chairs, and there are 2 fewer blue chairs than yellow chairs. In the afternoon, Lisa borrows 3 chairs. How many chairs are left in Rodrigo's classroom?
[Answer]There are 2 * 4 red chairs = 8 yellow chairs. There are 8 yellow chairs - 2 = 6 blue chairs. Total in the morning there were 4 red + 8 yellow + 6 blue = 18 chairs. After Lisa removed chairs there were 18 - 3 chairs = 15 chairs remaining. The answer is 15.
Q: Justin needs to collect one flower for each classmate that is in his 2nd-grade class. It takes him on average 10 minutes to find a flower he likes. He has been gathering for 2 hours. Assuming he has lost 3 of the flowers he initially gathered, how many more minutes does he need to look if he has 30 classmates?
A: If he gathers for 2 hours, the number of minutes gathering is 2 * 60 minutes per hour = 120 minutes of gathering flowers. Gathering for 120 minutes / 10 minutes per flower = 12 flowers gathered. If he gathers 12 flowers initially but lost 3, he has 12 - 3 = 9 flowers gathered and kept. Since he has 30 classmates total and has 9 flowers, he needs to gather 30 - 9 = 21 more flowers. Assuming it takes 10 minutes per flower, it will take him 10 * 21 = 210 minutes to gather the remaining 21 flowers needed. The answer is 210.
Question: Faith's neighborhood, with a total of 20 homes, decided to install solar panels. Each home needed 10 panels capable of providing their power needs. The supplier of the panels brought 50 panels less than the required amount. The neighbors agreed to only install the panels up to where they'd be finished. How many homes had their panels installed?
Answer:
The total number of panels required is 20 * 10 = 200 panels. When 50 failed to be delivered, the total number available for use became 200 - 50 = 150 panels. If each home requires 10 panels, the number of homes that had panels installed is 150 / 10 = 15 homes. The answer is 15.
