A printer will produce 80 wedding invitations for $210. The price to produce 120 invitations is $290. The printer uses a linear function to determine the price for producing different amounts of invitations. How much will the printer charge to produce 60 invitations? $120.00
$145.00
$157.50
$170.00

 $145.00

Step-by-step explanation: Since it costs $290 to print 120 invitations and you need to find out the cost of 60 which is half of 120 you would simply take the cost of 120 invitations which is $290 and divide that by 2 which equals $145.00.

D) $170

Step-by-step explanation:

To figure out how much each invitation costs we need to subtract 210 from 290 to get 80. Now we need to divide the cost by the difference of how many invitations were bought, 120-80=40. 80 divided by 40 = 2. so now we know each invitation costs $2. Now we are looking for the piice of 60 invitations. So we now need to multiply 2 times 20, because the difference between 80 and 60 is 20, to get 40. Now we need to subtract 40 from 210 to get 170. Own answer is $170 for 60 invitations.

Hope this Helps! Have a great day!
