Question

Two professional gamers subscribe to twitch streamers. Jonah has 430$ saved up, and spends 45$ a month on

subscriptions. Rodrick has 310$ saved up, and spends 25$ a month on subscriptions.
A) Create an equation that can be used to find m, the number of months it will take for both gamers to have the
same amount of money left?
B) After how many months will the gamers have the same amount of money?

Answer 1

A)
`430-45m = 310-25m`

B) 6 months

Explanation:

A) for Jonah, the equation would be
`430-45m`

Because the money is being spent on the subs, you subtract that from his original savings.

The same thing is said for Rodrick, but his equation would be
`310-25m`

to find out the number of months it will take for both gamers to have the

same amount of money left, you set their equations equal to each other:

`430-45m = 310-25m`

B) you solve for m.

`430-45m = 310-25m`

first by subtracting 310 on both sides to get:

`430-310-45m=-25m`

`120-45m=-25m`

then add 45m on both sides because we cant have negative months

`120=-25m+45m`

`120=20m`

divide by 20 on both sides to get the number of months

`(120)/(20) =(20m)/(20)`

`m=6`
