First find the increase in rent by multiplying last year's rent by 30%: $1000 * .3 = $300. Then find the food cost increase by multiplying last year's costs by 50%: $200 * .5 = $100. Then find the new car insurance price by multiplying last year's price by 3: $100 * 3 = $300. Then subtract the cost of car insurance last year from this year's price to find the increase: $300 - $100 = $200. Now find how much Jessica's monthly expenses increased by adding the increases in each of the three costs: $300 + $100 + $200 = $600. Now multiply the increase per month by the number of months in a year to find the annual increase: $600 / month * 12 months / year = $7200 / year.
The answer: 7200
Reverse engineering the question: Last year Jessica paid $1000 for rent, $200 for food, and $100 for car insurance each month. This year her rent goes up by 30%, food costs increase by 50%, and the cost of her car insurance triples because she was at fault in an accident. How much more does Jessica pay for her expenses over the whole year compared to last year?

Maila read 12 x 2 = 24 pages today. So she was able to read a total of 12 + 24 = 36 pages since yesterday. There are 120 - 36 = 84 pages left to be read. Since she wants to read half of the remaining pages tomorrow, then she should read 84 / 2 = 42 pages.
The answer: 42
Reverse engineering the question: Julie is reading a 120-page book. Yesterday, she was able to read 12 pages and today, she read twice as many pages as yesterday. If she wants to read half of the remaining pages tomorrow, how many pages should she read?

He has to read 350 pages a week because 7 x 50 = 350. He has read 262 pages because 43 + 65 + 28 + 70 + 56 = 262. He has to read 88 pages on Saturday because 350 - 262 = 88.
The answer: 88
Reverse engineering the question: Berry wants to make sure he reads an average of 50 pages a day. This week he read 43 pages on Sunday, 65 pages on Monday, and 28 pages on Tuesday. He had a soccer game and fell asleep early on Wednesday so he read nothing. On Thursday he read 70 pages, and on Friday he read 56 pages. How many pages does he have to read on Saturday to reach his goal?

She works 8 hours a day for $18 per hour so she makes 8 * 18 = $144.00 per 8 - hour shift. She works 10 hours a day and anything over 8 hours is eligible for overtime, so she gets 10 - 8 = 2 hours of overtime. Overtime is calculated as time and a half so and she makes $18 / hour so her overtime pay is 18 * .5 = $9.00. Her overtime pay is 18 + 9 = $27.00. Her base pay is $144.00 per 8 - hour shift and she works 5 days and makes 5 * $144 = $720.00. Her overtime pay is $27.00 per hour and she works 2 hours of overtime per day and makes 27 * 2 = $54.00 in overtime pay. 2 hours of overtime pay for 5 days means she makes 54 * 5 = $270.00. In 5 days her base pay is $720.00 and she makes $270.00 in overtime pay so she makes $720 + $270 = $990.00.
The answer: 990
Reverse engineering the question:
Tina makes $18.00 an hour. If she works more than 8 hours per shift, she is eligible for overtime, which is paid by your hourly wage + 1/2 your hourly wage. If she works 10 hours every day for 5 days, how much money does she make?
