28.80 + .20X = X
.20X = X - 28.80
1/5 = .20
X/5 = X -28.80
X = 5X - 144
Set the new X equal to the original X
28.80 + .20X = 5X - 144
172.8 + .20X = 5X
172.8 = 4.8X
36 = X
36$ is the original price
To check,
28.80 + (.20 x 36) = 36
28.80 + 7.2 = 36
36 = 36
A+S=589
S=a-61
A+A-61=589
2a=589+61
2a=650
A=325
S=325-61
S=264
Hope this helps

Work Shown:

Answer:
$14.80
Step-by-step explanation:
I'm assuming you meant to put 3.20 since $320 a mile would be ridiculous.
C(n)=2.00+3.20n
If n = 4 miles we have:
C(4)=2+3.20(4)
C(4)=2+12.80
C(4)=14.80
So the cost of the taxi is $14.80.
