Quandaries and Queries


The organizers of the walkathon want to have brochures printed to advertise the event. They get cost estimates from two printing companies. The costs are given by the equations.

Company A : C= 15 + 0.10n
Company B : C= 0.25n

For what number of brochures is the cost the same for both companies?

Thank you,Sir.



In your equations n is the number of brochures and C is the cost, one for each company. If the costs for the two companies are the same then

15 + 0.10n = 0.25n

Solve for n.
