Answer 2

What variable are we supposed to use for the DVD players?

Answer 3

it doesnt say

Answer 4

x= # of MP3 players
113-x= # of DVD players
35x = profit on MP3 players
18(113-x)=profit on DVD players

Now you can write the expression for the total profit.

Answer 5

15x+18(113-x) ?

Answer 6

Did you make a typo?

Answer 7

yes. 35x

Answer 8

Answer 9

and then what

Answer 10

What does the problem ask you to find?

Answer 11

they want the total profit

Answer 12

And so what is the answer?

Answer 13

They don't ask for the total profit. They ask for the EXPRESSION for the profit.

Answer 14

Write an expression...that's what it says

Answer 15

yea, but then where i enter the answer it says " total profit in dollars = "

Answer 16

Write an expression for the combined total profit (in dollars)

Answer 17

all i have so far is 35x+18(113-x)

Answer 18

So I see this has turned into a reading problem instead of a math problem.

total profit in dollars = 35x+18(113-x)

Answer 19

The directions ask you to write an expression for the profit in dollars and then it asks profit in dollars =

Answer 20

the answer was actually 17x+2034

Answer 21

So they wanted the simplified form. Who knew.
