Answer: ![\Large\boxed{290+5m=985}](https://tex.z-dn.net/?f=%5CLarge%5Cboxed%7B290%2B5m%3D985%7D)
Step-by-step explanation:
<u>Given information</u>
Initial cost = $290
Total cost = $985
Number of months = 5 months
Cost each month = ?
<u>Set variable</u>
Let [ m ] be the cost each month
<u>The equation in verble sense</u>
Initial paid + Extra each month = Total cost
<u>Convert verbal equation to mathematical sense</u>
$290 + 5m = $290
Therefore, to find the extra amount paid each month, the equation is ![\Large\boxed{290+5m=985}](https://tex.z-dn.net/?f=%5CLarge%5Cboxed%7B290%2B5m%3D985%7D)

<em>EXTRA </em><em>The following will be solving the derived equation, please ignore this part if it is useless for you.</em>
<u>Given equation</u>
290 + 5m = 985
<u>Subtract 290 on both sides</u>
290 + 5m - 290 = 985 - 290
5m = 695
<u>Divide 5 on both sides</u>
5m / 5 = 695 / 5
m = $139
Hope this helps!! :)
