Question

Debra's rectangular vegetable garden measures 9 1/3 yards by 12 yards. A bottle of garden fertilizer costs $14.79. If Debra needs to mix 1/8 cup of fertilizer with water for each square yard of her garden, how many cups of fertilizer does she need?

Answer 1

Answer:12=w

Step-by-step explanation:

64ft= 40 + 2w

-40 -40

24= 2w

24/2= 2w/2

12= w

Answer 2

Recall:

$\text{Area } = \text{Length} \times \text{Breadth}$

Find the area of the garden:

$\text{ Length } = 9\dfrac{1}{3} \text{ yd}$

$\text{ Breadth } = 12 \text{ yd}$

$\text{Area } = \text{Length} \times \text{Breadth}$

$\text{Area } = 9\dfrac{1}{3} \times 12$

$\text{Area } = \dfrac{28}{3} \times 12$

$\text{Area } = 112 \text{ yd}^2$

Find the amount of the fertiliser needed:

$1 \text { yd}^2 = \dfrac{1}{8} \text { cup}$

$112 \text { yd}^2 = \dfrac{1}{8} \times 112$

$112 \text { yd}^2 = 14 \text { cups}$

Answer: She needs 14 cups of fertiliser.
