An electrician charges a flat fee plus an hourly rate for a service call. She charges a total of $94 for a 3-hour service call on Monday and $130 for a 5-hour service call on Tuesday. How much should she charge for a 2-hour service call?

First you need to find what the hourly rate is and what the flat rate is. The hourly rate is $18 and the flat rate is $40. Then you add $40+ (18x). Substitute 2 in for x for the hours and get $76.

When the charge for 3 hours is $94 on Monday and $130 for 5- hour service on Tuesday would charge for 2-hour call service is $76.

Electricians charge a fixed rate + an hourly rate. The charges are a total of $94 for a 3-hour service call on Monday and $130 for a 5-hour service call on Tuesday.

How to solve the linear equation?

A linear equation is a one-degree equation. The equation includes the variable of the highest power one. The standard form of an equation is Ax + B = 0, where x is the variable, A is the coefficient and B is a constant.

To solve the linear equation we need to find the unknown variable which satisfied the given linear equation.

Electricians charge a fixed rate + an hourly rate

If he charges, $94 for a 3-hour call on Monday and $130 for a 5-hour call on Tuesday then charging for 2 extra hours is the difference between the two amounts.

130 - 94 = $36

for an hourly rate, it will be $18

For the fixed traveling charge, we will subtract the 3-hour rate from a fixed rate of $94 - 3 × $18 = $40

So, for x hour call the equation will be, 40 + 18x

for 2 hour service, the charges would be 40 + 18 × 2 = $76

Therefore, when the charge for 3 hours is $94 on Monday and $130 for 5- hour service on Tuesday would charge for 2-hour call service is $76.
