Show your work for the following problem. Michael wants a new iPhone. The total cost of the phone is $1249. He can pay $43 down with so much each month added to his bill for 24 months. How much extra will be added to each bill for the next 2 years?

7.25 dollars

Step-by-step explanation:

1249 - 43 = 1206

1206 divided b7 24 = 50.25

He can pay 43 dollars, bu he needs to pay 50.25, as a result he needs 7.25 more dollars.

50.25 - 43 = 7.25

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
