Hi again. I don't understand these two questions so um please help me. Also explain me how to do it. Please

1. An electrician charges $40 to come to your house. She also charges $55 for each hour that she works. The electrician charges you a total of $190. How many hours does the electrician work at your house?

2. A taxi charges $1.75 plus a fee of $0.75 for each mile traveled. The total cost of a ride, without a tip, is $4.75. How many miles is the trip? Use m for the numbers of miles traveled.

(190 - 40) / 55 = ?

1.75 + 0.75m = 4.75

Thank you!

You're welcome.

Of course! Let me help you understand and solve these two questions step by step.

1. To determine the number of hours the electrician worked at your house, we need to set up an equation based on the given information.

Let's break it down:
- The electrician charges $40 just to come to your house, so this is a fixed cost.
- She also charges $55 for each hour that she works, so this cost will vary based on the number of hours worked.
- The total charge for the work done at your house is $190.

To find the number of hours, we can set up the following equation:
$40 (fixed cost) + $55 for each hour = $190 (total charge)

To solve this equation and find the number of hours, we can subtract the fixed cost from the total charge and then divide by the cost per hour.

Calculation:
$190 - $40 = $150
$150 ÷ $55 = 2.727

We find that the electrician worked for approximately 2.727 hours. Since we cannot have fractional hours, let's round it to the nearest whole number. Therefore, the electrician worked for approximately 3 hours at your house.

2. Similar to the first question, we need to set up an equation to find the number of miles traveled in the taxi ride:

Let's break it down:
- The taxi charges a fixed fee of $1.75
- The taxi also charges a fee of $0.75 for each mile traveled.
- The total cost of the ride, without a tip, is $4.75.

To find the number of miles traveled, we can set up the following equation:
$1.75 (fixed fee) + $0.75 for each mile = $4.75 (total cost)

To solve this equation and find the number of miles, we can subtract the fixed fee from the total cost and then divide by the cost per mile.

Calculation:
$4.75 - $1.75 = $3.00
$3.00 ÷ $0.75 = 4

So, the trip is approximately 4 miles.

I hope this explanation helps you understand how to solve these two questions! Let me know if there's anything else I can assist you with.
