Question

I don't understand please help

Answer 1

So for the first problem;
You will take the cost of the glue $2.39 and take away the cost of the tape. Which is $1.99
$2.39 - 1.99$
$= 0.40$

So the answer to problem 1. will be $0.40 more.

For the second problem;
We will add the cost of the markers together, then add the cost of the paper onto that.
$4.50 + \times 2 + 3.79$
$9 + 3.79$
$= 12.37$
Leaving the second answer to be $12.39.
