Art bought $100 worth of stock and gained $25 per year. kiley bought $400 dollars worth of another stock and lost $35 per year. use x for time and y for stock value. write and graph equations to represent each situation. when did art and kiley have the same amount of stock value?

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
