Step-by-step explanation:
1. Let's review the information given to us to answer the question properly:
Length of the garden = 12 yards
Width of the garden = 9 1/3 = 9.33 yards
Cost of a bottle of fertilizer = $ 14.79
Ratio of fertilizer : water for the garden = 1/8 cup for each square foot
2. How many cups of fertilizer did she need?
For answering the question, we need to know the area of the garden and convert it to square feet, this way:
Area = Length of the garden * width of the garden
Area = 12 * 9.33 = 111.96 square yards, that we will round to 112
Let's recall that 1 square yard = 9 square feet
Area = 112 * 9 = 1,008 square feet
Now, we can calculate the cups of fertilizer needed:
Cups of fertilizer = 1,008/8 = 126
Finally, for calculating how many bottles of fertilizer does Debra need to buy, let's assume that each bottle has a quart because that information wasn't given to us.
Let's recall that 1 cup = 1/4 quart
126 cups = 32 quarts ⇒ 32 bottles
Cost of 32 bottles of fertilizer = 32 * 14.79
Cost of fertilizer = $ 473.28
