Answer:
4n + 100 = C
7n = C
by elimination 7n - 4n - 100 = 0
3n = 100
n = 100/3 (33.33)
*need to sell 34 pizzas
n= number of pizzas
c= cost

Complete Question:
The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.
Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?
Answer:
The height is 36 meters
Step-by-step explanation:
Given

Required
The interpretation of the question is to determine the value of y when x = 15
Substitute 15 for x in: 



<em>The height is 36 meters</em>

Answer:I = prt
p = 7430
r = 5%....turn to decimal = 0.05
t = 3
I = (7430)(0.05)(3)
I = 1114.50 <===
