Ray bought two kinds of tennis balls at two different prices. The Bouncies cost $3 for a set and the Yellows cost $5 for each set. How many sets of Bouncies did Ray purchase if he spent a total of $49 on 11 sets of tennis balls?

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

the answer is c hope it
