Please help meee!!!!

Answer 1

The key words here are less than and 3 times. Knee pads are represented by the variable k, and 3 times that price would be 3k. Now, skateboards are $5 less than that price, so the expression that gives the price of a skateboard is 3k - $5.

Answer 2

First of all k=15 and all you have to do is multiply by 5 and 3 and get the answer of 15 then divide it by 3 and get the answer of 5
