a computer repair shop fixes about 18 computers per week when it charges $100 per computer. for each $10 increase, the shop fixes 3 fewer computers per week. create an expression that represents the charges per week.
Answer
Explanation:
Step1: Let the number of $10 - dollar$ increases be $x$.
The charge per computer is $100 + 10x$.
Step2: Find the number of computers fixed per week.
The number of computers fixed per week is $18-3x$.
Step3: Calculate the total charges per week.
The total charges per week $C=(100 + 10x)(18 - 3x)$.
Answer:
$(100 + 10x)(18 - 3x)$
