An advertiser goes to a printer and is charged $37 for 90 copies of one flyer $53 for 285 copies of another flyer. This printer charges a fixed setup cost plus a charge for every copy of single-page flyers. Find a function that describes the cost of a printing job, if x is the number of copies made.

Step-by-step explanation:

that is the function you are looking for.

first, we know that it is a fixed set up cost and charge for individual paper

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
