Question

#1

Answer 1

Answer:

Equation: y = 0.25x + 7.50

Cost: $10.50

Step-by-step explanation:

Let x be the number of miles and y be the total cost in $.

y = 0.25x + 7.50

If we want to find the total cost of a 12 mi trip, we plug in x=12.

y = 0.25 * 12 + 7.50

y = 3 + 7.50

y=10.50

Answer 2

The requested equation is


C(m) = 7.50 + 0.25*m,


where C(m) is the total cost (in dollars) for "m" miles.
