Question 878522: there are two items for sale. The ratio of the first item's price to the second is 5:2. the total price of both items is $21. What is the price of the first item? Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! A + B = 21
If the ratio is 5:2, that's 7 total units.
Divide 21 by 7 to get 3.
5(*3):2(*3)
15:6
The first item costs $15; the second, $6
