Dr. Coleman is ordering PHS t-shirts for the staff. Half of the shirts are maroon and the other half are grey. A local store sells t-shirts for $5 per shirt and a starting fee of $80. What would be the cost of buying 200 t-shirts?
Let
y -----> the total cost
x ----> the number of shirts
we ahve that
the linear equation is
y=5x+80
For x=200
substitute
y=5(200)+80
y=$1,-080
therefore
