Answer:
Step-by-step explanation:
The printer charges a $27 set-up fee, plus $0.75 for each poster. The set up fee is constant.
The cost y in dollars to print x posters is given by the linear equation
y=0.75x+27.
a) To find the cost, y in dollars to print 50 posters, we will substitute 50 for x in the given linear equation. It becomes
y=0.75x+27
y = 0.75 × 50 +27
y = 37.5 +27 =$64.5
b) To find the cost, y in dollars to print 100 posters, we will substitute 100 for x in the given linear equation. It becomes
y=0.75x+27
y = 0.75 × 100 +27
y = 75+27 =$102
