i.
To use the function notation to write an equation that gives the total charges for repairing a computer.
i.
Answer to Problem 11CP
The equation is,
Explanation of Solution
Given:
The shop charges flat $50 plus $35 per hour spent on computer repair
Calculation:
Let, “h” be the number of hours spent on the computer repair.
Now forming an equation using function notation,
Where, f(h) is the total charges
H is the time spent on computer repair.
Graph:
Conclusion:
The equation is,
ii.
How much will the shop charge if computer repair shop spent 2.5 hours on it.
ii.
Answer to Problem 11CP
The computer shop will charge $ 137.5
Explanation of Solution
Given:
The shop spends 2.5 hours on the repair, equation for the charges the computer will take
Calculation:
Substituting the value of hours in the equation,
Hence, the charges the computer shop will take,
$ 137.5
Conclusion:
The computer shop will charge $ 137.5
iii.
How many hours did the repair shop spent on the repairing?
iii.
Answer to Problem 11CP
The repair shop spent 3.5 hours in repairing.
Explanation of Solution
Given:
The repair shop charges $172.50
Calculation:
Substituting the values of charges in the equation formed,
Shifting left-hand side value to right hand-side,
Cross-multiplying the values,
Conclusion:
The repair shop spent 3.5 hours in repairing.
