The director would have to pay $40.47.
If each scholar eats one slice of pizza, then there would be two pizza pies because 8 slices plus another 8 slices in 16
8+8=16
If all of them eat another .5 slice, adding up the halves would equal 8
.5 x 16 = 8
In total, the director would have to buy three pizzas which equals up to our total of $40.47
Answer: B. |x-100| = 25
Explanation:
Draw out a number line. Mark 75, 100 and 125 on the number line as points A, B, and C in that order. Don't worry about the spacing.
The value of x represents where the train is. So if we had say x = 85, then it would be at location 85 on the number line. Writing |x-100| is the distance from x to 100. The absolute value ensures the distance is never negative. We want this distance to be 25 because after traveling 25 cm, the switch is turned, and the train goes the other way.
