The auto repair on First Street charges a flat fee of $15 plus $10 an hour for servicing a car. The auto repair shop on Second A
Lilit [14]

Answer:

3 hours

Step-by-step explanation:

Let's express number of hours required for servicing as: x

The auto repair on First Street charges a flat fee of $15 plus $10 an hour for servicing a car.

This is expressed mathematically as:

$15 + $10 × x

= 15 + 10x

The auto repair shop on Second Avenue charges no flat fee but $15 an hour for servicing a car

This is expressed as:

$15 × x

= 15x

The number of hours Malik's car needs to be serviced in order to be able to pay the same amount of money at both shops is calculated as:

Charges by Auto repair shop on First street = Charges by Auto repair shop on Second Avenue

15 + 10x = 15x

15 = 15x - 10x

15 = 5x

5x = 15

x = 15/5

x = 3 hours

Therefore, the number of hours Malik's car needs to be serviced in order to be able to pay the same amount of money at either auto repair shops is 3 hours

Khloe and Emma work at a furniture store. Khloe is paid $245 per week plus 9.5% of her total sales in dollars, xx, which can be
ale4655 [162]

Answer: Their weekly pay would be the same if xx equals $1,600

Step-by-step explanation: The first and most important step is to identify what the question requires, and that is, what is the value of the unknown in the equation of their weekly incomes that would make their pay to be the same? Their weekly pay as per individual is given as follows;

Khloe = 245 + 0.095x ———(1)

Emma = 285 + 0.07x ———(2)

Simply put, we need to find the value of x when equation (1) equals equation (2)

245 + 0.095x = 285 + 0.07x

Collect like terms and we now have

0.095x - 0.07x = 285 - 245

0.025x = 40

Divide both sides of the equation by 0.025

x = 1600

Therefore their weekly pay would be at the same level, if x equals $1600
