Answer:
$13.60
Explanation:
First let's find how much Gerry spends on lunch in 2 weeks (assuming she goes to school 5 days a week):
$1.25*10=$12.50
Now we find out how much she pays for the extra snack. Since in 2 weeks there are 2 Fridays then:
0.55*2=$1.10
Then we add these two together to get:
$12.50+$1.10=$13.60
