Caitlyn used 4 43-cent stamps and 8 6-cent stamps

<h3>How many of each stamp did Caitlyn use?</h3>

The given parameters are:

Amount paid = $2.20

Stamp used: 43-cent stamps and 6-cent stamps

Represent the amount of stamps in dollars

$0.43 and $0.06

Let the count of these stamps be x and y

So, we have:

0.43x + 0.06y = 2.20

Multiply through by 100

43x + 6y = 220

Let x = 4.

So, we have:

43* 4 + 6y = 220

This gives

6y = 48

Divide by 6

y = 8

Hence, Caitlyn used 4 43-cent stamps and 8 6-cent stamps
