Question

The organizers of a walkathon get cost estimates from two printing companies to print brochures to advertise the event. The costs are given by the equations below, where C is the cost in dollars and n is the number of brochures. Company A: C=15+0.10n Company B: C=0.25n. For what number of brochures are the cost the same for both company’s

Answer 1

15 + 0.10n = 0.25n
15 = 0.25n - 0.10n
15 = 0.15n
15 / 0.15 = n
100 = n....they are the same at 100 brochures
