Lillian studied for an exam at a coffee shop. She bought a muffin for $4, a coffee for $2, and a sandwich for $5. If she came into the coffee shop with $15, how much did she have when she left?

Question

how much did she have left.

Answer 1

Lillian's original amount was $15. To solve the problem, find out how much she spent in the coffee shop and subtract it from her original amount. Your problem should look something like this:

$15 - ($4 + $2 + $5) =

Once you've added the numbers in the parenthesis, your equation should look like this:

$15 - $11 =

Solve.

$15 - $11 = $4
