[Question]Roe saved $10 per month from January to July and saved $15 per month from August to November. How much should she save in December so she will have a total savings of $150 in the year?
[Answer]Since there are 7 months from January to July, then Roe's savings for those months sum up to $10 x 7 = $70. Since there are 4 months from August to November, then her savings for those months sum up to $15 x 4 = $60. Her total savings from January to November is $70 + $60 = $130. Therefore, she needs to save $150 - $130 = $20 in December. The answer is 20.
Q: If 24 out of every 60 individuals like football and out of those that like it, 50% play it, how many people would you expect play football out of a group of 250?
A: If 50% of individuals that like football play it, and there are 24 out of 60 individuals that like it, then 24 * 50% = 12 out of 60 individuals play it. If 12 individuals play it out of 60 individuals then that means only 12 / 60 = 1 / 5 or 20% play it. If 20% of individuals play football out of a group of 250 people, one would expect 250 * 20% = 50 individuals to play it. The answer is 50.
Question: A shopping center sells T-shirts at $8 each, a sweater at $18, and a jacket at $80. The jacket is on sale with a 10% discount. The sales tax is 5%. Kevin wants to buy six T-shirts, four sweaters, and five jackets for his children. How much does Kevin have to pay for all the items, including the sales tax?
Answer: The six T - shirts cost 6 x $8 = $48. The four sweaters cost 4 x $18 = $72. And five jackets normally cost 5 x $80 = $400. So, a discount of 10 / 100 x $400 = $40 for the five jackets. Thus, the selling price of the five jackets is $400 - $40 = $360. Hence, the total cost of all the items is $48 + $72 + $360 = $480. The sales tax is equal to 5 / 100 x $480 = $24. Therefore, Kevin has to pay $480 + $24 = $504. including the sales tax. The answer is 504.
[Question]A shady restaurant is charging customers gratuities after taxes without them being aware. If my total bill was $140, the sales tax in my city is 10%, I ordered a NY Striploin for $80, and I ordered a glass of wine for $10, how much did they charge me for gratuities?
[Answer]The total bill before taxes or gratuities was $80 for the steak + $10 for the wine = $80 + $10 = $90. If the tax is 10%, then the taxes paid were $90 * 10% = $9. That means that the total bill before gratuities was $90 + $9 = $99. If the final bill was $140, then you were charged $140 - $99 = $41 for gratuities. The answer is 41.
