Answer:
40+4.5p=112, and 16
Step-by-step explanation:
Roger always starts off with the same $40. Then, he gets $4.5 for every pair of shoes he sells. So, if the number of shoes sold is p, we then have the equation:
40+4.5p=112
The next part of the question asks for us to solve this equation, basically. We subtract 40 from both sides:
4.5p=72
p=72/4.5 (Divide both sides by 4.5)
p=16
