Question

Emily went to Kroger to buy some fruit. She needs a dozen apples and some bananas. A dozen organic apples costs $11.45 and each organic banana costs 1.05 a piece. Emily went to Trader Joe's to compare prices. At Trader Joe's a dozen apples costs $13.45 and each organic banana 97 cents a piece. Write an equation for how many bananas Emily would have to buy for Kroger and Trader Joe's to be the same cost. Use 'b' as the variable. Use the format of Kroger=Trader Joe's

Answer 1

1.05(b) = 0.97(b)

Explanation:

What you know from the problem:

Krogers:

11.45(12)+1.05(b)

Trader Joe's:

13.45(12)+0.97(b)

Kroger = Trader Joe's

1.05(b) = 0.97(b)
