Answer 1

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: $y=35h+12$ where h is number of hours and y is cost

Put h=4 and find cost

$y=35h+12\\y=35(4)+12\\y=140+12\\y=152$

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

$C=32h+20\\C=32(4)+20\\C=128+20\\C=148$

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
