Answer:

A) 48

B) 3 seconds

Step-by-step explanation:

A) -16+40+24 = 48

B) -16t² + 40t + 24 = 0

2t² - 5t - 3 = 0 (÷ by -8)

2t² - 6t + t - 3 = 0

2t(t -3) + 1(t - 3) = 0

(t - 3)(2t + 1) = 0

t = 3, t = -½

Johnny is selling tickets to a school play. On the first day of ticket sales he sold 14 senior citizen tickets and 4 child ticke
FrozenT [24]

Johnny is selling tickets to a school play. On the first day of ticket sales he sold 14 senior (S) citizen tickets and 4 child (C) tickets for a total of $200. On the second day of ticket sales he sold 7 senior (S) citizen tickets and 1 child (C) ticket for a total of $92. What is the price of one child ticket?

14S + 4C = 200

14S = 200 - 4C

S = (200 - 4C)/14

7S + 1C = 92

7S = 92 - C

S = (92 - C)/7

(200 - 4C)/14 = (92 - C)/7

7 x (200 - 4C) = 14 x (92 - C)

1400 - 28C = 1288 - 14C

1400 - 1288 = 28C - 14C

112 = 14C

C = 112/14 = 8

the price of one child ticket = $8

  2. Lets consider what mod does as a commands: If you have 7 and then mod it by 2 ie 7%2 you get 1
  3. Essentially mod is seeing how many times a # goes into the other number and finding the remainder.
  4. In this case we want the remainder of 2: -8%3 =-2
  5. note there is also a mathematical procedural way to solve this.
