Question

The last time Caralina visited the post office, she spent $4.49 to mail letters and packages. Each letter cost $0.37 to mail, while each package cost $0.88 to mail. if she sent two more letters than packages, how many letters did she mail?

Answer 1

5 letters

Explanation:

let x = # of packages

x+2 = # of letters

$0.37(x+2) + $0.88x = $4.49

.37x + .74 + .88x = 4.493

1.25x + .74 = 4.49

1.25x = 3.75

x = 3.75/1.25 = 3 = # of packages

# of letters = x+2 = 3+2 = 5
