Answer 1

8x + 8y

Explanation:

Each obstacle course has 2 jump rope stations and 2 pogo stick stations.

There are 4 obstacle courses

So total number of jump rope stations = 4 x 2 = 8

Each jump rope station requires x jump ropes
So total number of jump ropes needed = 8x

Each pogo stick stations. requires y pogo sticks
So total number of pogo sticks needed = 8y

Expression to represent how many jump ropes and pogo sticks Mr. Vincent needs in all is

8x + 8y
