Jihan's favorite baseball team is one game away from making it to the playoffs. Each regular season ticket costs $15 and each playoff ticket costs $40. If Jihan wanted to take two friends to the last regular season game and one friend to a playoff game, how much money would she need?

Answer

70

Step-by-step explanation:

2friends=30 1playoff=40 15+15=30+40=70

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
