### 3-18. If five notebooks cost $5.25, how much would three notebooks cost?

Explanation

The cost of the notebooks is directly proportional to the number of notebooks. If five notebooks cost $5.25, then the cost of one notebook is $5.25/5 = $1.05. Therefore, the cost of three notebooks would be 3 x $1.05 = $3.15.Rate this question:

### 3-21. Stacy exercises three days each week by walking around the soccer field near her home. The field is 80 yards wide and 115 yards long.1. Draw a diagram of the field. Then find how far Stacy walks in one trip around the field. This distance is called the perimeter.

Explanation

Stacy walks around the soccer field, which has a width of 80 yards and a length of 115 yards. To find the perimeter, we add up all the sides of the field. The width is 80 yards and the length is 115 yards, so we add 80 + 115 + 80 + 115 = 390 yards. Therefore, Stacy walks a distance of 390 yards in one trip around the field.Rate this question:

### 3-21. Stacy exercises three days each week by walking around the soccer field near her home. The field is 80 yards wide and 115 yards long. (Use your answer from the last question to help you solve this one.)2. If Stacy walks around the field four times each time she exercises, how far does she walk each week?

Explanation

Stacy walks around the soccer field four times each time she exercises. The field is 80 yards wide and 115 yards long. To find out how far she walks each time, we need to calculate the perimeter of the field. The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, the length of the field is 115 yards and the width is 80 yards. So, the perimeter of the field is 2(115) + 2(80) = 230 + 160 = 390 yards. Since Stacy walks around the field four times, she walks a total of 390 x 4 = 1560 yards each time she exercises. Therefore, in a week, she walks 1560 x 3 = 4680 yards.Rate this question:
