Question

a family buys a pretzel hamburger and drinks for 28.75 then gives two 20bills how much money should give back

Answer 1

The total amount paid by the family for the pretzel hamburger and drinks is $28.75. They paid with two $20 bills, which totals:

\[
2 \times 20 = 40
\]

Now, to find out how much change they should receive, subtract the total cost from the amount paid:

\[
40 - 28.75 = 11.25
\]

So, the family should receive $11.25 in change.
