An appliance store has $1000 to spend on stocking personal CD players and personal cassette players. The CD players cost $50 and the cassette players cost $20. Write an inequality to model the different numbers of CD players and cassette players the store can buy.

 C)(3, 3.9)(65, 84.5)(24, 31.2)
 
Explanation:

Ou choice is C) and we just need to prove that 17:22.1 = 3:3.9. First, we will change the ratios into fractions so that



To prove the above equation we use cross multiplication so that

17(3.9) = 3(22.1)
66.3 = 66.3

Which is a true equation. Therefore, 17:22.1 = 3:3.9.
