<span>This problem can be easily
solved using algebra.<span>
Since
James wants to know how many months he will have $810, we need to simplify it in an equation.</span></span>
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
<span>Therefore, it will take 5
months for James to save in order to get $810 in his bank account.</span>
