Answer:

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
