Question

The cost to mail a package is $5.00. Noah has postcard stamps that are worth $0.34 each and first-class stamps that are worth $0.49 each. a. Write an equation that relates the number of postcard stamps p, the number of first-class stamps f, and the cost of mailing the package.

Answer 1

`0.34p + 0.49f = 5.00`

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`
