The expression represents the total cost of the computer repair, including taxes.
[tex]0.08(70h)+70h[/tex]"h" represents the number of hours that takes to repair the computer.
The total cost of the service is calculated as the ground price plus the taxes. The taxes are a percentage of the ground price.
For example, let's say that the ground price is "2x" which indicates that the cost is $2 per time unit represented by the variable "x", if the tax is 1% of the ground price, you can calculate said percentage by multiplying the ground price by 1% and divide it by 100:
[tex]\frac{1\%\cdot2x}{100\%}=\frac{1\%}{100\%}(2x)=0.01(2x)[/tex]The taxes in this example will be expressed by the term "0.01(2x)" and the total cost can be expressed as "2x+0.01(2x)"
If you apply the logic followed in the example for the given expression:
"70h" represents the ground price for the computer repair, which means that it costs $70 per hour.
And the term multiplied by the decimal value "0.08(70h)" represents the taxes she has to pay for the repair.
