Solve this problem using estimation.
melissa bought 18 cupcakes and 2 gallons of fruit punch for her valentine party. if the cupcakes cost $.28 each and the punch costs $2.78 a gallon, estimate her total bill.

If each cupcake costs 0.28 cents then you times that by how many she got (18) which turns into $5.04. 

Fruit punch a gallon is $2.78 times that by two since she got two gallons and it turns out to be $5.56 .
You add

$5.04 and $5.56 together and the answer is $10.60

Ugh h h t t u i i vick u
