Question

An Internet service has a monthly access fee of $24.95 and a connection fee of $0.25 per hour. The function y=0.25x+24.95 represents the total cost y of Internet use for x hours. If Bonnie uses the Internet for 7 hours and Billy uses the Internet for 4 hours, how much more did Bonnie spend for Internet access than Billy?

Answer 1

To find the difference in cost between Bonnie's 7 hours and Billy's 4 hours of Internet use, the function y=0.25x+24.95 is applied to both. Bonnie's total cost is $26.70, and Billy's is $25.95, meaning Bonnie spent $0.75 more than Billy.

Step-by-step explanation:

To calculate the difference in Internet access costs between Bonnie and Billy, we need to apply the given function y=0.25x+24.95 to the number of hours each used the Internet. For Bonnie, who used the Internet for 7 hours, the cost is y=0.25(7)+24.95. For Billy, who used it for 4 hours, the cost is y=0.25(4)+24.95.

Calculating these:

• Bonnie: y = 0.25(7) + 24.95 = 1.75 + 24.95 = $26.70
• Billy: y = 0.25(4) + 24.95 = 1.00 + 24.95 = $25.95

The difference in cost is $26.70 - $25.95 = $0.75. Therefore, Bonnie spent $0.75 more than Billy for Internet access.
