Number line graph with closed circle on 30 and shading to the right
because you already have 30 dollars and they need at least 120 but if they get more then 120 they can still hold the science fair.
Since the equation is:
<span>P(x)=-5x^2+40x-300
Solving the equation by using the calculator, the values for x are:
x = 4.72
Therefore, the company must sell 8 items per week to maximize the profit.

Answer:
The number of ounce of topping that can be get is 4 .
Step-by-step explanation:
Given as :
The cost of a sundae = $3
The cost for each extra ounce of toppings = $0.50
Let The number of ounce of topping = n
The total spending cost on sundae with n extra topping = $5
Now, According to question
The total spending cost on sundae with n extra topping = The cost of a sundae + The number of ounce of topping × The cost for each extra ounce of toppings
Or , $3 + n × $0.50 = $5
or, 3 + 0.50 n = 5
or , 0.50 n = 5 - 3
or, 0.50 n = 2
∴ n = 
I.e n = 4
So, The number of ounce of topping = n = 4
Hence The number of ounce of topping that can be get is 4 . Answer
