Question

A package of 8 frankfurters costs $5.00 and a package of 12 hot dog buns costs $3.00. If Jeffrey makes a hot dog sandwich using only a frankfurter and a bun, what percent of the cost of his hot dog sandwich comes from the bun?

Answer 1

Buns= 28.57%

Step-by-step explanation:

Giving the following information:

A package of 8 frankfurters costs $5.00 and a package of 12 hot dog buns costs $3.00.

First, we need to calculate the unitary cost of the frankfurters and buns.

Frankfurters= 5/8= $0.625

Buns= 3/12= 0.25

Now, the percentage of buns per hotdog:

Total unitary cost= 0.625 + 0.25= 0.875

Buns= 0.25/0.875= 0.2857= 28.57%
