Question

Camille had $18.90 to spend on groceries. After buying 10 grapefruits, she had $3.90 left. If each grapefruit costs the same amount, what is the price of one grapefruit?
David has a garden with dimensions 11 feet long x 9 feet wide. He wants to enlarge the garden to an area of 126 square feet. How much farther will he need to extend the length of the garden to attain his desired area?

Answer 1

Answer:

Step-by-step explanation:

10g=18.9-3.9

10g=15

g=15/10

g=1.5

So each grapefruit costs $1.50

(L+d)9=126 and the original length was 11ft so

(11+d)9=126

99+9d=126

9d=27

d=3

So he needs to extend the length by 3ft
