Step-by-step explanation:
<u><em>The complete question is</em></u>
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
Let
n ---> the number of brochures.
C ---> the cost in dollars
we have
<em>Company A</em>
----> equation A
This is the equation of a line in slope intercept form
where
The slope or unit rate is
The y-intercept or initial value is
<em>Company B</em>
----> equation B
This is a proportional relationship
where
The constant of proportionality or slope is
To find out for what number of brochures are the costs the same for both companies, equate equation A and equation B
Solve by substitution method
solve for n
