To print flyers, Speedy Ads charges 2.5 times the cost of paper, p, plus $15, represented as 2.5p + 15. Fast Flyers charges 4.5 times the cost of paper, p, an $8 discount, represented as 4.5p – 8. Calculate the cost of printing flyers if the total cost is the same for each company.

$30.50
$21.35
$11.50
$43.75

AND

A student showed work to solve the equation 6(3d +1) – 40 = 9d +8 for d.


6(3d + 1) – 40 = 9d + 8
Step One 18d + 6 – 40 = 9d + 8
Step Two 18d – 46 = 9d + 8
Step Three 9d – 46 = 8
Step Four 9d = 54
Step Five d = 6
The student made a mistake in Step Two. Choose the correct equation for Step Two.
–16d = 17d
24d – 40 = 9d + 8
18d – 34 = 9d + 8
18d + 46 = 9d + 8
