The answer is 14 minutes

Step-by-step explanation:

Subtract your total and divide what you have left. $20 - $18.04 = $1.96

You spent a total of $1.96

Divide that by 0.14 how much per minute and you get 14 minutes.

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

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
