Liliana brought 5 pounds 7 ounces of apples to make candy apples. Apples cost 13 cents per ounce. How much did sarah mom spend on apples. Express your answer in dollars

11.31 $

Step-by-step explanation:

Given in question that

total apple brought to make candy apples = 5 pounds 7 ounce

since 1 pound = 16 ounce

so, 5 pounds = 5 x 16 = 80 ounces

therefore total apple brought = 80 + 7 = 87 ounces

again,

cost of 1 ounce = 13 cents

so, cost of 87 ounces = 13 x 87 = 1131 cents

now,

we know that 1 cent = 0.01 dollar

so, 1131 cents = 0.01 x 1131 = 11.31 $
