Doug's Plumbing Company charges $30 up front and $50 per hour while Penny's Plumbing Company charges $192 up front and $176 per hour. Doug has decided to double both of his prices, and Penny has decided to cut both of her prices in half. After how many hours of work would it be cheaper to hire Penny?

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
