A printer estimates the cost of printing a newspaper as $500 plus $5.50 per copy. Write in symbols a formula

Write in symbols a formula for the relationship between the cost of the magazine and the quantity produced. Use this formula to determine:

a) The cost of printing 580 copies of newspaper

b) The # of newspaper that would attract a cost of $610

A= 500+5.50x ( formula)

a) A=500+5.50(580)
A= $3690 (coast)

b) 610=500+5.50(x)
10=5.50x
x=1.81 ( number of newspaper)

that sounds about right
