The price of a holiday was decreased by 12% to £600. What was the price before the decrease? Give your answer to the nearest penny.

Explanation:

If a price decreases by 12%, then you pay the remaining 88%. Notice how 88% + 12% = 100%

If x is the original price before the discount, then 0.88x represents the price after the discount, which is 600 pounds.

0.88x = 600

x = 600/0.88

x = 681.818 approximately

x = 681.82 pounds

Another way to look at it.

x = original price before discount

12% of x = 0.12x = amount you save

x - 0.12x = (1-0.12)x = 0.88x = final price after discount = 600

The steps afterward are the same as above.

If the original price is £681.82, and the discount is 12%, then you save 0.12*681.82 = 81.8184 = 81.82 pounds. So the final price is 681.82 - 81.82 = 600 pounds which verifies the answer.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
