Answer:
We can set the two expressions equal to each other since the total cost is the same for each company:
2.5p + 15 = 4.5p - 8
Simplifying this equation:
15 + 8 = 4.5p - 2.5p
23 = 2p
p = 11.5
Now that we know the cost of the paper, we can substitute it into either expression to find the total cost:
Speedy Ads: 2.5(11.5) + 15 = 43.75
Fast Flyers: 4.5(11.5) - 8 = 43.75
Therefore, the cost of printing flyers if the total cost is the same for each company is $43.75.
