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
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
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
