Question

In order to make a profit, a retailer sells dresses at 130% of the price she paid for them. A dress in the shop priced at $78.95. How much did the retailer pay for it?

Answer 1

Answer:

$102.635

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 78.95 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 78.95 is 100%, we can write it down as 78.95=100%.

4. We know, that x is 130% of the output value, so we can write it down as x=130%.

5. Now we have two simple equations:

1) 78.95=100%

2) x=130%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

78.95/x=100%/130%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 130% of 78.95
