B, x=6
i already did this and this was the answer
b) 8
they were asking you about the rate of increase in students per year
so you take increase in students/years= (224-120)/(2005-1992)=104/13=8
To solve this problem and calculate the security's equilibrium rate of return, you should sum<span> the security's default risk premium (2.00%),</span> the inflation risk premium (1.75%), the real risk-free rate (3.50%), the security's liquidity risk<span> premium (0.25%) </span><span>and the maturity risk premium (0.85%). So, you have:
ij*=2.00%+1.75%+3.50%+0.25%+0.85%
</span> ij*=8.35%<span>
</span>
<u>Part (a)</u>
The variable y is the dependent variable and the variable x is the independent variable.
<u>Part (b)</u>
The cost of one ticket is $0.75. Therefore, the cost of 18 tickets will be:
dollars
Now, we know that Kendall spent her money only on ride tickets and fair admission and that she spent a total of $33.50.
Therefore, the price of the fair admission is: $33.50-$13.50=$20
If we use y to represent the total cost and x to represent the number of ride tickets, the linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission can be written as:
......Equation 1
<u>Part (c)</u>
The above equation is logical because, in general, the total cost of the rides will depend upon the number of ride tickets bought and that will be 0.75x. Now, even if one does not take any rides, that is when x=0, they still will have to pay for the fair admission, and thus their total cost, y=$20.
Likewise, any "additional" cost will depend upon the number of ride tickets bought as already suggested. Thus, the total cost will be the sum of the total ride ticket cost and the fixed fair admission cost. Thus, the above Equation 1 is the correct representative linear equation of the question given.
