Question

Suppose you got 8 mangoes and 3 apples for $18 and 3 mangoes and 5 apples for $14.50. How much does each mango and each apple cost? (I already know both equations but need help solving for M.)

Answer 1

Please look at my question.

Answer 2

Well, what are your equations?

Answer 3

8m + 3a= 18 and 3m + 5a= 14.50

Answer 4

now, via substiution or elimination some for M and A

Answer 5

think of what number can the entire first equation be multiplied by and the same for the next to cancel (or eliminate) M

Answer 6

I don't know which variable in which equation to sole for first.

Answer 7

doesn't matter - either one is fine...

Answer 8

multiply first equation by -3 and the 2nd one by 8 in order to cancel out the M

Answer 9

I need help.
I don't know what to do.

Answer 10

8m + 3a= 18 and 3m + 5a= 14.50 Are your equation right?

So what we do is solve the first one for a, okay?

So first isolate a and get: 3a = -8m +18, then divide by 3, so you get: a = (8/3)m + 6.

Now that you know a, put this in the second equation and get m. Once you have m, plug into 1 of two original equations to get the actual value of a.

Answer 11

Alright I'll try.

Answer 12

Does m= 1.5?

Answer 13

???????

Answer 14

I got it.
THANKSTO EVERYONE FOR YOUR HELP!
