Answer 1

500 + 100m = 1000 + 50m

Explanation:

In order to form an equation we need atleast on variable which in this scenario would be the number of months (m). We can say that we know that sooner or later their savings will equal. Therefore, we can create the following equations for each of their savings progress which are equal to one another...

500 + 100m = 1000 + 50m

This equation if solved would give us the value of 10 for the variable m, meaning that their savings will equal in 10 months. To find out how much each will have in 10 months we can simply grab one half of the equation and substitute 10 for m

500 + 100(10) = x

500 + 1000 = x

1500 = x

Finally, we can see that after 10 months they would both have $1500 saved up.
