In a movie theater, the admission costs $8 but the price is $3 less if you watch the movie before 6 P.M. Kath takes her 2 siblings and 3 of her friends to a movie which starts at 4 P.M. How much will Kath pay for all of their admission? Think carefully first, then make a decision:
The movie theater admission costs $8 - $3 = $5 before 6 P.M. Kath will pay for herself, her siblings, and her friends, so that is a total of 1 + 2 + 3 = 6 people. So, Kate will pay $5 x 6 = $30 for all their admission. So, the answer is 30.
