For the 1st hour the cost is $50 whatever is the duration (providing it's 1 hour max.

From one hour and onward the cost becomes an additional $25 per quater of an hour.

If y is the cost and x the number of hours, then the equation becomes :

y =50 + 0.25.x or y =1/4x + 50

Answer: A


Step-by-step explanation:

Which statement describes the relationship between labor cost and time for a car repair?

All repairs requiring 1 hour or less have the same labor cost.

Labor costs the same no matter how many hours are used for a repair.

Labor costs for a repair are more expensive as the number of hours increases.

There is no cost of labor for a repair requiring less than 1 hour.

Gnesinka [82]

Answer:

<em>How the sales tax de-calculator works </em>

Stevie and Michael share their profit in a ratio 3:5. Stevie gets £120 more than Michael. How much profit did they make altogeth
Airida [17]

Answer:

£480

Step-by-step explanation:

we can multiply both terms of ratio with same number without changing the ratio.

Example

a:b = ax: bx (here we have multiplied both terms with x)\

Given

Stevie and Michael share their profit in a ratio 3:5

Let the profit for Stevie and Michael be 3x and 5x

Given Stevie gets £120 more than Michael

Profit for Steve = 120 + profit for Michael

3x = 120 + 5x

3x-5x = 120

=> -2x = 120

=> x= -120/2 = -60

As we see profit is negative , hence it cannot be solution.

It can be solved if Stevie and Michael share their profit in a ratio 5:3

(note: in ratio , bigger number should have bigger term in ratio)

Let the profit for Stevie and Michael be 3x and 5x

Given Stevie gets £120 more than Michael

Profit for Steve = 120 + profit for Michael

5x = 120 + 3x

5x-xx = 120

=> 2x = 120

=> x= x120/2 = 60

Profit for stevei = 5x =5*60 = 300

Profit for Michael = 3x = 3*60 = 180

Total profit for them together = 300 + 180 = 480 Answer.

Find the diameter of the object.
Anni [7]

Answer:

1 \frac{1}{5} centimeters

Step-by-step explanation:

The diameter is equal to the radius × 2. We know that the radius is equal to 3/5 centimeters.

To solve this you must do \frac{3}{5} × 2.

This equals \frac{6}{5}, or 1 \frac{1}{5} cm.
