Avideo store has 20 copies of a movie that each rent for $3 a day. if 75% of these copies are rented on one and 90% of these copies rented the next day how much money was collected from renting this movie on both days

Money collected from renting the movies on both days = $99

Explanation:

We are given that the total number of copies is 20 and that the rent of each is $3 a day

1- On the first day:

Number of copies rented = 75% of the number of copies

Number of copies rented = 0.75 * 20 = 15 copies

Money made from renting the copies on first day = 15 * 3 = $45

2- On the second day:

Number of copies rented = 90% of the number of copies

Number of copies rented = 0.9 * 20 = 18 copies

Money made from renting the copies on second day = 18 * 3 = $54

3- Getting the total amount of money from renting:

Total collected money on both days = 45 + 54 = $99

Hope this helps :)

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
