Respuesta :
let x be the number of miles Chang drove
.79x
so it goes as this
$16.99+$.79x=$152.08
$16.99-$16.99+$.79x=$152.08-$16.99
$.79x=$135.09
x=$135.09/.79
x=171 miles
152.08-16.99= 135.09
135.09/ 0.79 = 171
He drove 171 miles.
I subtracted the base fee. And after that I was left with everything from the miles he drove.
So then I divided the miles by how much he had to pay per mile.
135.09/ 0.79 = 171
