Question

Jamal and his friends are conducting a car wash to raise money for a school play. Over the first weekend they raised $336.00, which was 80% of what they set out to earn. If they collect $21 for each car they wash, how many more cars must they wash?

Can someone help me?

Answer 1

helping

Answer 2

So first thing, you would divide 336 by 0.80 which gives you 420

Answer 3

Thats how much they set out to earn.

Answer 4

The equation would be 21x + 336 = 420

Answer 5

Solve for x and done

Answer 6

now thats where you are wrong

Answer 7

Explain please

Answer 8

I am now

Answer 9

21x = 420 - 336

Answer 10

21x = 84

Answer 11

x = 84/21 or 4 more cars

Answer 12

ok, what you are figuring out is right, but that is not what the question asks

Answer 13

x is the number of cars here

Answer 14

you need to find:

x= 420/21

Answer 15

@hyperlunatic that is what the question is asking for, not too sure what you're trying to get at but it will most likely just confuse @kayleedilbeck

Answer 16

no because it says HOW MANY MORE CARS MUST THEY WASH

Answer 17

They've already collected 336 of the 420

Answer 18

they earn 21 for every car

Answer 19

21x= 420 - 336

Answer 20

Yeah the 420 answer confused me. I put in the number 4 for how many more cars are needed to be washed and that was the answer but not really sure how you got 4

Answer 21

21x = 84

Answer 22

x = 4

Answer 23

no that was just step 1 @kayleedilbeck

Answer 24

Sorry for the confusion

Answer 25

It's okay, thank you!
