A. $0.80
B. $7.76
C. $9.76
D. $12.24

Answer 1

Answer: B. $7.76

=========================================

Step-by-step explanation:

Ignore the info about how much Margo spent.

Anthony spent $10.24 on lunch, before the tip. Then we add on the $2 tip to get a total of 12.24 dollars spent.

The amount of change is 20-12.24 = 7.76

----------------

Here's how the cashier can mentally figure out how much change to give

Start with the number of cents from $12.24

The jump from 24 cents to 100 cents is 76 cents (24+76 = 100)

This gets us from 12.24 to 13.00

The jump from 13 to 20 is another 7 dollars.

So that's how we get 7 + 0.76 = 7.76 in change

Answer 2

7.76 is your answer
