3.

All fruit is $0.80 per pound.Converting fractions to decimals, 1/8 = 0.125 and 1/4 = 0.25.We can multiply these decimals and 0.8 together to find the price paid for each fruit.When you do it correctly,here are your answer.

Apples:$0.10

Pears:$0.20

Bananas$1

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
