Answer:

0.34p + 0.49f = 5.00

Step-by-step explanation:

Given

Cost = \$5.00

Postcards = \$0.34

First-class = \$0.49

Required

Represent as an equation

If 1 postcard costs $0.34, then p postcards cost $0.34p

If 1 first-class costs $0.49, then f first-class cost $0.49f

The addition of p postcards and f first-class equals the total cost of mailing the package.

So, we have:

0.34p + 0.49f = 5.00
