Q: Antonella has ten Canadian coins in her purse that are either loonies or toonies. A loonie equals $1 and a toonie equals $2. If she bought a $3 Frappuccino and still has $11, how many toonies did she initially have?
A: If Antonella spent $3 and now has $11, that means initially she had $3 + $11 = $14. Let the number of loonies Antonella had be L and the number of toonies be T. Initially she had in her purse a total of 1L + 2T = $14. We also know that she had 10 coins in total or 10 = L + T. That means initially she had T = 10 - L toonies. Combining both equations we know that 14 = 1L + 2 * (10 - L). If we multiply through the parentheses, we get 14 = 1L + 20 - 2L. If we combine the variables on one side and the constants on another, we get - 6 = - 1L or L = 6. Knowing the value of L, we can solve for T = 10 - L = 10 - 6 = 4. The answer is 4.
Question: Tony has $87. He needs to buy some cheese, which costs $7 a pound and a pound of beef that costs $5 a pound. After buying the beef and his cheese, he has $61 left. How many pounds of cheese did he buy?
Answer: He spent $26 because 87 - 61 = 26. He spend $21 on cheese because 26 - 5 = 21. He bought 3 pounds of cheese because 21 / 7 = 3. The answer is 3.
[Question]Remi prepared a tomato nursery and planted tomato seedlings. After 20 days, the seedlings were ready to be transferred. On the first day, he planted 200 seedlings on the farm. On the second day, while working alongside his father, he planted twice the number of seedlings he planted on the first day. If the total number of seedlings transferred to the farm on these two days was 1200, how many seedlings did his father plant?
[Answer]On the second day, he planted 2 * 200 seedlings = 400 seedlings. The total number of seedlings Remi planted on the two days is 400 seedlings + 200 seedlings = 600 seedlings. If the total number of seedlings transferred from the nursery was 1200 after the second day, Remi's father planted 1200 seedlings - 600 seedlings = 600 seedlings. The answer is 600.
Q: John used to go to the gym multiple times a weak but because of lockdowns he hasn't been able to go. He used to lift 700 for squat, 400 for bench, and 800 for deadlift. For squat he lost 30% of his lift. He didn't lose any weight on bench because he was able to train that at home and he lost 200 pounds on deadlift. What is his new total?
A: He lost 700 * .3 = 210 pounds on squat. So his squat is now 700 - 210 = 490 pounds. His deadlift is 800 - 200 = 600 pounds. So his total is now 490 + 600 + 400 = 1490 pounds. The answer is 1490.
Question: Jacob is making s'mores. Each s'more takes two graham crackers and one marshmallow. If Jacob has 48 graham crackers and 6 marshmallows, how many more marshmallows does he need to buy?
Answer: First find the number of marshmallows Jacob needs: 48 graham crackers / 2 graham crackers / marshmallow = 24 marshmallows. Then subtract the number of marshmallows Jacob already has from the number he needs to find the number he needs to buy: 24 marshmallows - 6 marshmallows = 18 marshmallows. The answer is 18.
Q: One barnyard owl makes 5 hoot sounds per minute. If 5 less than 20 hoots per minute are heard coming out of the barn, how many Barnyard owls would this noise be coming from?
A:
5 less than 20 hoots per minute is 20 - 5 = 15 hoots per minute. If one barnyard owl makes 5 hoot sounds per minute, then 15 hoots per minute are coming from 15 / 5 = 3 barnyard owls. The answer is 3.
