[Question]A plant supplier was able to sell 20 pieces of orchids for $50 each and 15 pieces potted Chinese money plant for $25. The money he earned was then used to pay his two workers $40 each and to buy new pots worth $150. How much money was left from the plant supplier's earnings?
[Answer]The plant supplier earned $50 x 20 = $1000 for the orchids. He earned $25 x 15 = $375 for the potted Chinese money plants. So, his total earnings was $1000 + $375 = $1375. Then he paid $40 x 2 = $80 to his workers. He used a total of $80 + $150 = $230 for the worker's pay and new pots. Hence, he was left with $1375 - $230 = $1145 from his earnings. The answer is 1145.

[Question]Dan is digging graves for a family killed by COVID-19. If it takes Dan 3 hours to dig an adult grave and 2 hours to dig a child's grave, how long does it take him to dig 5 adult graves and one child's grave?
[Answer]First find the total amount of time Dan spends digging adult graves: 3 hours / grave * 5 graves = 15 hours. Then add the time to dig the child's grave to find the total time he spends digging: 15 hours + 2 hours = 17 hours. The answer is 17.

[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?
[Answer]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 is 41.

[Question]Tim rides his bike back and forth to work for each of his 5 workdays. His work is 20 miles away. He also goes for a weekend bike ride of 200 miles.  If he can bike at 25 mph how much time does he spend biking a week?
[Answer]
He bikes 20 * 2 = 40 miles each day for work. So he bikes 40 * 5 = 200 miles for work. That means he bikes a total of 200 + 200 = 400 miles for work. So he bikes a total of 400 / 25 = 16 hours. The answer is 16.
