Answer:

Step-by-step explanation:
So we have the equation:

First, distribute the 7 into the (x+8) and simplify:

Combine the like terms 7x and 8x by adding them together:

Subtract 56 from both sides to isolate the x:

Divide both sides by 15 to get x:

Let x be the number of days and y represent miles driven.
Since it costs 25 per day, you multiply 25 by x.
25x
10 cents (otherwise known as .1 dollars) per mile, multiply .1 times y. Now add the two.
.1y
25x+.1y
The answer is <span>a.) 25x + 0.1y</span>.
The solution to the quadratic equation is option D
