$490.50 was the original price of the ski set
To solve- you multiply 327 and 0.2 (20%) which equals 65.4
Then you multiple 327 and 0.3 (30%) which equals 98.1
To find the final original price, you add up 65.4,98.1, and 327
Then to double check your answer, you can take 30% and then 20% of the originally price and subtract them from the original price
I hope my answer was clear enough!
I don't know if it is correct but here goes nothing 8*(d-3)
The answer would be
Slope is -7
Let's turn this into a fraction using the given information we already have.

We want the denominator, or the bottom part of the fraction, to be 1 in order for us to have a unit rate.
This fraction can be simplified if we divide both the numerator and denominator by 3.
Numerator: 18/3 = 6
Denominator: 3/3 = 1
Now we have

Any number divided by 1 is equal to that number.

Thus, your unit rate is 6 miles per hour.
Have an awesome day! :)
