Question

You have the choice of logging on at one of two Internet cafés. Their posted rates are as follows:

Log-On Café: $6.25 plus $0.25 for every minute online

eCafé: $7.00 plus $0.20 for every minute online

Which café is the best option if you plan on using the Internet for 55 minutes? What is the equation that relates the number of minutes used and the total cost, and how much money will you save?

Answer 1

A. Log-On Café, the equation is C = $0.25M + $6.25 ,and I'll save $0.75
B. Log-On Café, the equation is C = $0.625M + $2.50, and I'll save $2.00
C. eCafé, the equation is C = $0.70M + $2.00, and I'll save $0.75
D. eCafé, the equation is C = $0.20M + $7.00, and I'll save $2.00

Answer 2

To understand this question well, you'll need to find the function representing the cost you'll pay at each cafe if you stay logged on for x minutes.

Next, let x = 55 minutes and calculate the total cost payable at each cafe.

Next, determine the difference in the total costs.

Hint: The appropriate equation of a straight line is y = mx + b.
