Ups charges $7 for the first pound, and $0.20 for each additional pound. fedex charges $5 for the first pound and $0.30 for each additional pound. let p represent the number of pounds. how many pounds will it take for ups and fedex to cost the same? explain.
write an equation and solve (hint: since it is asking you about costing the same, think about what goes on either side of the equals sign).

( answer soon, this is due today)

The answer is 20 pounds.

Step-by-step explanation:

Let p represent the number of pounds.

UPS charges $7 for the first pound, and $0.20 for each additional pound.

FedEx charges $5 for the first pound and $0.30 for each additional pound.

To know the number of pounds it will take for UPS and FedEx to cost the same, we will equal both the equations.

=>

=>

=> p = 20

Hence, it will take 20 pounds to make both equal.

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
