Answer:
Charge(x) = $60 + ($0.75/mile)x, where x is the number of miles driven.
Step-by-step explanation:
That $60 is the y-intercept and represents the (flat) charge per session. The ($0.75/mile)x represents the amount charged for the total number of miles driven.
Let the digit in the tens place be x
tens place = x (therefore the value is 10x)
ones place = x + 7
The number is 10x + x + 7
Add 26 to it
10x + x + 7 + 26 = 11x + 33
It is 5 times the sum of the digit
11x + 33 = 5(x + x + 7)
11x 33 = 10x + 35
x = 2
x+ 7 = 2 + 7 = 9
So the number is 29
