since 15 is half of 30 it is very simple subtraction. so 15 is 1/2 of 30 you automatically have 15 (the other half) and then add the 2 so 17 is the answer :)

Answer:

To solve [tex]32-15[/tex] we just have to subtract as follows

[tex]32-15=17[/tex]

Now, this can be modelled as a problem like the following:

Mark weighs 32 pounds and he wants to lose more weight. Doing exercises he lose 15 pounds, how many pounds does Mark weigh after the lose?

As you can see, this problem is solve with a subtraction like the one we did above

[tex]32lb-15lb=17lb[/tex]

Therefore Mark now weighs 17 pounds.
