find the actual discount, multiply the discount rate by the original amount 'x'. To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price. Solve the equation and find the original amount 'x'.
Step-by-step explanation:
Sale Price = $11.34 (answer). This means the cost of the item to you is $11.34. You will pay $11.34 for a item with original price of $12.60 when discounted 10%. In this example, if you buy an item at $12.60 with 10% discount, you will pay 12.60 - 1.26 = 11.34 dollars.
1 1/2 - 2 1/2 is 3/2:5/2 or a 3:5 ratio 2 2/5 - 4 is 12/5:20/5 or a 3:5 ratio 3 3/4 - 6 1/4 is 15/4:25/4 or a 3:5 ratio 4 - 6 2/3 is 12/3:20/3 or a 3:5 ratio 1.2- 2 if divided by .4 is a 3:5 ratio 1.8-3 if divided by .6 is a 3:5 ratio the unit rate is 3:5 Since all units are 3:5 it is proportional
