On saturday, mrs. armor bought seven pairs of socks for three dollars each, and a sweater for her dog for $12. then she found a five dollar bill on the sidewalk. over the course of saturday, what was the change in the amount of money mrs. armor had?

First she bought 7 pairs of socks for $3 each

7 x 3 = $21

Then she bought she a sweater for her dog for $12

The total amount of money she spent:

$21 + $12 = $33

Then she found a $5 bill

So the difference of money is +5

She has 5 more dollars then what she had to begin with

Because she found $5, opposed to spending $33 of her money, she really spent $28 because she found $5

Hope this helps
