Answer:
1.
2.
Step-by-step explanation:
Let the number of people in the group be x. Denote the total cost as C.
1. If the regular cost is $21 per person, then the total regular cost for x people is
2. If the special cost is $8 per person, then the total special cost for x people is There is an additional $104 fee for a private room, thus the total special cost is
As 64 is a perfect cube, the coefficient part does not present any problems. However, for the variable with an exponent, it is easier to obtain the cube root by multiplying the exponent by (1/3), since the cube root operator is equivalent to raising a number to the power of (1/3). This is shown below:
cube root (64x^12) = 4 * x^(12)(1/3) = 4 *x^4
Therefore, the answer is 4x^4.
The total demand is: 200 + 400 + 250 + 350 = 1200
Production is 350 a month.
Multiply by the 4 months: 350 x 4 = 1400.
Now subtract the demand from the total production:
1400 - 1200 = 200 left for inventory.
The answer is b. 200
The answer to the question above is B.)
