Answer:
a) The Total fee, that Mike charges for 4 hours of instruction is $152
b) The total fee, that Tony charges for 4 hours of instruction is $148
c) The difference between total fee Mike and Tony charge for 4 hours of instructions is $4
Step-by-step explanation:
a) What is the total fee, that mike charges for 4 hours of instruction.
Mike charges $12 for travel expenses and $35 per hour for instruction.
So, the equation will be:
where h is number of hours and y is cost
Put h=4 and find cost
![y=35h+12\\y=35(4)+12\\y=140+12\\y=152\\](https://tex.z-dn.net/?f=y%3D35h%2B12%5C%5Cy%3D35%284%29%2B12%5C%5Cy%3D140%2B12%5C%5Cy%3D152%5C%5C)
So, the Total fee, that Mike charges for 4 hours of instruction is $152
b) What is the total fee, that Tony charges for 4 hours of instruction
Tony's fee can be modelled by C=32h+20 where h is number of hours and C is cost
Put h=4
![C=32h+20\\C=32(4)+20\\C=128+20\\C=148](https://tex.z-dn.net/?f=C%3D32h%2B20%5C%5CC%3D32%284%29%2B20%5C%5CC%3D128%2B20%5C%5CC%3D148)
So, the total fee, that Tony charges for 4 hours of instruction is $148
c) What is the difference between total fee Mike and Tony charge for 4 hours of instructions.
Cost for Mike = $152
Cost for Tony = $148
Difference = 152 - 148 = 4
So, the difference between total fee Mike and Tony charge for 4 hours of instructions is $4
