Answer:
The new amount is 36
Step-by-step explanation:
we know that
100%+20%=120%
Let
x-----> the new amount
The number 30 represent the 100%

30/100%=x/120%
x=120*30/100=36
Answer:
2.4 i am pretty sure
Step-by-step explanation:
you just have to work backwards
Hey there!!
Given equation :
... c(x) = 29x + 54.5
<em>In this equation $54.50 is installation fee and this would remain as a constant. ( This value wouldn't change ). </em>
<em>'x' is represented as the number of months. </em>
The total cost or c(x) is given as $344.50
Getting this into equations :
... 344.50 = 29x + 54.5
Subtracting 54.5 on both sides :
... 29x = 290
Dividing by 29 on both sides :
... x = 10
<u><em>Hence, the number of months is 10. </em></u>
Hope my answer helps!!
