Question

Yolanda purchased 12 eggs for $1.56. At this rate, how much will 18 eggs cost?

Answer 1

Ratio:

cost / number of eggs

1.56 / 12

For 18 eggs:

Cost / number of eggs = x/18

Equal both expressions:

1.56/12 = x/18

Solve for x:

0.13 = x/18

0.13 (18) = x

x=2.34

18 eggs will cosr $2.34
