we have the expression for the cost
In this problem we havesubstitute the given values in the expression to obtain the cost
Answer: you are correct
Step-by-step explanation:
Answer: 110
Step-by-step explanation:
Given;
Total cost C = $151
Enrollment fee E = $30
Charge per 10 test t = $11
n is the number of packet of test taken.
The questions can be represented by the equation below;
30 + 11n = 151
Substracting 30 from both sides.
11n = 151-30 = 121
n = 121/11
n = 11
Since the number of packet of test is 11 and each packet contains 10 tests. The number of test N is given by;
N = 10 n = 10 ×11 = 110
N = 110
A=10x(15x)-p(4x)^2
A=150x^2-16px^2
A=(150-16p)x^2
