All you do is solve for z. So 8z-13=7. To solve for a variable you have to do the opposite to cancel out the numbers on each side. First you add 13 over to 7 to cancel out 13 on the z side. So 8z=20 is what you have left. Then you divide 8 on both sides to cancel out 8 on the z side. what you are left with is z=2.5. Lastly you plug and check. 8(2.5) - 13 = 7, 20-13=7. And thats correct so z is 2.5.
Answer:
b
Step-by-step explanation:
Answer:
The answer is "Option A and Option B"
Step-by-step explanation:
In question 1:
The fixed cost=2621.21

Calculating the total cost for 45 boat slips:

In question 2:
It is the pure fixed costs that remain consistent in total regardless of dynamic loads. An overall cost B both for 1000 and 2000 unit is unchanged, therefore the Cost B is a fixed sum.
The answer to this question is 14 degrees Fahrenheit.
