Answer:
$34.25
Explanation:
If you are charging 12.25 a month you can write an equation with the variable m representing months and t representing the total cost.
12.25m = t
Since it is asking for 7 months plug 7 into m.
12.25(7) = t.
Multiply 12.25 by 7 to find the total cost after 7 months.
t = 85.75.
Therefore the total for 7 months is $85.75
To find how much is in the original equation we need to subtract the total from 120 by using the equation with r representing the remaining money:
120 - t = r
120 - 85.75 = 34.25
