Each medium box lunch purchased by Duff contains two sandwiches and three bags of chips. If sandwiches cost $7.75, what is Duff's total cost? *

$23.24

Step-by-step explanation:

This question assumes that each sandwich is 3 times the price of a bag of chips.

If a sandwich costs $7.75, a bag of chips would be:

= 7.75 / 3

= $2.58 per sandwich

The total cost of what Duff bought is therefore:

= (7.75 * 2) + (2.58 * 3)

= 15.5 + 7.74

= $23.24

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
