a monthly fee to download e books is 4.95, plus 3.99 per book downloaded. Write an equation that represents the total cost, c, in a month when b books are downloaded. Explain how your equation represents the problem.

c=4.95+3.99b

When there are no books, the service fee still applies, so when b=0, c=$4.95.

For each book downloaded $3.99 is added to the charge. The service fee is only charged once a month.

Step-by-step explanation:

Answer

4.95+3.99b=c

Step-by-step explanation:

When there are no books, the service fee still applies, so when b=0, c=$4.95.

For each book downloaded $3.99 is added to the charge. The service fee is only charged once a month.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
