Let S be the amount Alexis paid for the shoes. She spent S + 30 + 46 + 38 + 11 + 18 = S + 143. She used all but $16 of her budget, so S + 143 = 200 - 16 = 184. Thus, Alexis paid S = 184 - 143 = $41 for the shoes.
The answer: 41
Reverse engineering the question: Alexis is applying for a new job and bought a new set of business clothes to wear to the interview. She went to a department store with a budget of $200 and spent $30 on a button-up shirt, $46 on suit pants, $38 on a suit coat, $11 on socks, and $18 on a belt. She also purchased a pair of shoes, but lost the receipt for them. She has $16 left from her budget. How much did Alexis pay for the shoes?

Jennifer's home is 5 miles away from the first museum, so the round trip back and forth is 5 miles there + 5 miles back = 10 miles altogether. On another day Jennifer goes to a museum 15 miles away + 15 miles to return home = 30 miles total. Combined, Jennifer travels 10 miles on the first day + 30 miles on the second day = 40 miles Jennifer travels total.
The answer: 40
Reverse engineering the question: Jennifer wants to go to a museum. There is one 5 miles away from her home and one 15 miles away. If Jennifer goes to both museums on two separate days, how many miles total will she travel?

The drinks cost a total of $4 per drink * 2 drinks = $8. So the sandwiches cost a total of $26 total spending - $8 spending on drinks = $18. Therefore, each sandwich costs $18 for sandwiches / 3 sandwiches = $6.
The answer: 6
Reverse engineering the question: Wade has called into a rest stop and decides to get food for the road. He buys a sandwich to eat now, one for the road, and one for in the evening. He also buys 2 drinks. If the drinks cost $4 each and Wade spends a total of $26 then how much, in dollars, did the sandwiches each cost?

First, add the number of kosher meals to the number of vegan meals: 7 meals + 8 meals = 15 meals. Then subtract the three meals that are both kosher and vegan since they got counted twice: 15 meals - 3 meals = 12 meals. Finally, subtract that number from the total number of meals to find the number of meals that are neither kosher nor vegan: 30 meals - 12 meals = 18 meals.
The answer: 18
Reverse engineering the question:
Megan is delivering meals on wheels. Out of her 30 clients, 7 need vegan meals, 8 need kosher meals, and three people need meals that are both vegan and kosher. How many meals does Megan deliver that are neither kosher nor vegan?
