Question

Franklin deposited $75 in a no-interest bank account when he opened it. After that, he deposits $50 per month in the account. Assume he makes no other withdrawals or deposits. The equation below can be used to find m , the number of months it will take him to save a total of $175.

Answer 1

175 = 50m + 75 <<== ur equation

Answer 2

$75 + $50m = $175

Explanation:

First, he deposited $75 that don't depend on the number of months. After that, he deposits $50 per month.

So, in the first month he will have the initial $75 and $50, that is $75 + $50*1 = $125.

When we multiply by 1 it means that only one month passed.

We need to find out the number of months it will take him to save a total of $175. For that, we take the initial $75, we add $50 multiplied by the number of months and that have to equal $175.

$75 + $50m = $175

If we want to find out m, we subtract $75 on both sides of the equation and then divide it by $50:

$75 + $50m - $75 = $175 - $75

$50m = $100

$50m/$50 = $100/$50

m = 2
