Answer: Fall Out Boy's service is cheaper than Five Seconds of Summer's service.
Step-by-step explanation: The cost of Five Seconds of Summer's tutoring service can be represented by the equation:
C = 5 + 5h
where C is the total cost and h is the number of hours.
The cost of Fall Out Boy's tutoring service can be represented by the equation:
C = 9 + 3h
To compare the cost of the two services, we can use the substitution method. We can set the number of hours (h) equal to a variable and substitute that variable into the equation for both services.
For example, if we set h = 4 (4 hours of tutoring), we get:
C(Five Seconds of Summer) = 5 + 5(4) = 25
C(Fall Out Boy) = 9 + 3(4) = 21
The cost of Fall Out Boy's service is $21 and the cost of Five Seconds of Summer's service is $25. Therefore, Fall Out Boy's service is cheaper for 4 hours of tutoring.
We can also graph the cost of the two services on a coordinate plane. The x-axis represents the number of hours and the y-axis represents the cost. The equation for Five Seconds of Summer's service would be y = 5 + 5x and the equation for Fall Out Boy's service would be y = 9 + 3x
Service | Equation
Five Seconds of Summer y = 5 + 5x
Fall Out Boy | y = 9 + 3x
