James has $360 in his savings account. if he decides to save $90 every month, which of these best describes how many months it will take for him to have more than 810 in his savings account?

This problem can be easily solved using algebra.
Since James wants to know how many months he will have $810, we need to simplify it in an equation.
Let x = number of months
$360 + $90x = $810
We transfer $360 to the other side and reverse operation
$90x = $810 - $360
Now it is simplified to this
$90x = $450
n order to find the value of x, we divide 90 to both sides
$90x/90 = $450/90
…and arrive at the answer.
X = 5
Therefore, it will take 5 months for James to save in order to get $810 in his bank account.
