Answer:
The change received by the customer is $7.
Step-by-step explanation:
First, write the given expression for the change when paying with $50.

Evaluate the parentheses:

Now add the numbers inside the parentheses.

Subtract the numbers.

Hence, the change received by the customer is $7.
Answer:
B) 54
Step-by-step explanation:
A mode of a number set is the number the appears the most.
In the list given, 54 was the number that appeared the most.
We are given the functions:
<span>S (p) = 40 + 0.008 p^3 --->
1</span>
<span>D (p) = 200 – 0.16 p^2 --->
2</span>
T o find for the price in which the price of supply equals
demand, all we have to do is to equate the two equations, equation 1 and 2, and
calculate for the value of p, therefore:
S (p) = D (p)
40 + 0.008 p^3 = 200 – 0.16 p^2
0.008 p^3 + 0.16 p^2 = 160
p^3 + 20 p^2 = 20,000
p^3 + 20 p^2 – 20,000 = 0
Calculating for the roots using the calculator gives us:
p = 21.86, -20.93±21.84i
Since price cannot be imaginary therefore:
p = 21.86
