Option (4)

Step-by-step explanation:

We Fix it Computer Repair charges for it's services as per equation given as,

C = 30h + 90

Here, C = Total cost

h = Number of hours worked

This equation is in the form of a linear equation,

y = mx + b

Here, m = slope of the equation

And slope of the equation defines the unit rate

Therefore, charges for each hour of the first company = $30

Table given in the question represents the charges of another company John's Compute Repair.

There is a common difference in each successive term of the Total Cost of the table,

Common difference = 100 - 55 = 45

Therefore, this table represents a linear function.

Slope of the linear function passing through and is given by the expression,

Slope =

Slope of the function represented by the table =

                                                                              = 45

Therefore, per hour charges by the second company = $45

Difference in the charges = $45 - $30

                                           = $15

John's Computer Repair charges more by $15.

Option (4) is the correct option.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
