Reasoning and answer: Lisa's mother gave her 3 / 5 * $1200 = $720 for her birthday gift. She also received 2 * $720 = $1440 from her brother for the gift. If she still had to find $400 to fully reach her birthday gift cost, it means her gift's total cost was $1200 + $1440 + $720 + $400 = $3760.
The answer: 3760

First find the total number of inches of nylon used for the dog collars: 18 inches / dog collar * 9 dog collars = 162 inches. Then find the total number of inches of nylon used for the cat collars: 10 inches / cat collar * 3 cat collars = 30 inches. Then add the nylon needed for the cat and dog collars to find the total amount needed: 162 inches + 30 inches = 192 inches.

Reasoning and answer: First find how many inches the hem is by multiplying the length in feet by the number of inches per foot: 3 feet * 12 inches / foot = 36 inches. Then divide the length in inches by the length of each stitch to find how many stitches Jenna makes: 36 inches / .25 inches = 144 stitches. Then divide the number of stitches by Jenna's stitching rate to find how long it takes her: 144 stitches / 24 stitches / minute = 6 minutes.
The answer: 6

2 heads of lettuce at $1 apiece is 2 * $1 = $2. 4 tomatoes at $0.50 apiece is 4 * $0.5 = $2. Thus, each customer purchases $2 + $2 = $4 in lettuce and tomatoes per month. Therefore, if 500 customers per month spend $4 on lettuce and tomatoes, then the store will receive $4 * 500 = $2000 per month on sales of lettuce and tomatoes.
The answer: 2000
