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.

Given

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:

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

just sum

10 + 10 = 20
