As a fundraiser, a school club is selling posters. the printer charges a $27 set-up fee, plus $0.75 for each poster. then the cost y in dollars to print x posters is given by the linear equation
y=0.75x+27.

a. what is the cost y in dollars to print 50 posters? 100 posters?

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

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
