We have a question: Scout delivers groceries on the weekends. His base pay is $10.00 an hour. He also earns a $5.00 tip per customer that he delivers groceries to. On Saturday he worked 4 hours and delivered groceries to 5 people. Sunday he worked 5 hours and delivered groceries to 8 people. How much did he make over the weekend?
And an answer: 155
So how you got the answer?
He worked 4 hours on Saturday and 5 hours on Sunday for a total of 4 + 5 = 9 hours. His base pay is $10.00 an hour and he worked 9 hours for a total of 10 * 9 = $90.00. He delivered groceries to 5 people on Saturday and 8 people on Sunday for a total of 5 + 8 = 13 deliveries. He makes $5.00 per delivery and he delivered to 13 people so he made 5 * 13 = $65.00. His base pay is $90.00 and he made $65.00 in tips for a total of 90 + 65 = $155.00.

We have a question: An artist spends 30 hours every week painting. If it takes her 3 hours to complete a painting, how many paintings can she make in four weeks?
And an answer: 40
So how you got the answer?
She completes 30 hours / week / 3 hours / painting = 10 paintings / week. So in one month, she paints 10 paintings / week * 4 weeks / month = 40 paintings.

We have a question: Anne is 2 times as tall as her sister while Bella is 3 times as tall as Anne. If Anne is 80cm tall, what is the height difference between Bella and Anne's sister?
And an answer: 200
So how you got the answer?
Anne is 2 times as tall as her sister hence 2 * (her sister's height) = 80cm. Her sister's height = 80cm / 2 = 40cm. Bella is 3 times as tall as Anne hence Bella's height is 3 * 80 cm = 240 cm. The height difference between Bella and Anne's sister = 240 - 40 = 200cm.
