Write an equation to determine how many pairs of shoes, ppp, Roger must sell in a day to meet his daily earnings goal.

Question

Roger gets $40 per day as wages and $4.50 as commision fro every pair of shoes he sells in a day. his daily earning goal is $112.

Answer 1

You know, this used to confuse me reaaaaaally badly!

So, if he sells 2 pairs, he makes $4.50(2), right? He then gets his $40, for a total of $49.

So, selling p shoes gets him $4.50p in commission, right? He still gets his $40, and he wants to make $112 in all. Let's put it all together.

4.50p + 40 = 112

Hope this helps!
