The <em><u>correct answers</u></em> are:
The inequality is 75+4t ≥ 400, and they must sell at least 82 tickets.
Explanation:
t is the number of tickets sold. They start out with $75, so that is where our inequality begins. Each ticket is $4; this gives us the expression 4t. Together with the $75 carry over, we have 75+4t.
They must make at least $400 to pay for the dance. This means it must be more than or equal to 400; this gives us 75+4t ≥ 400.
To solve this, first subtract 75 from each side:
75+4t-75 ≥ 400-75
4t ≥ 325
Divide both sides by 4:
4t/4 ≥ 325/4
t ≥ 81.25
We cannot sell a portion of a ticket, so we round. While mathematically this number would "round down," if they only sell 81 tickets, they will not have enough money. Therefore we round up to 82.
Putting it into a calculator, we get 0.125 as our answer
Answer:
8.704%
Step-by-step explanation:
The computation of the before cost of debt is as follows
Given that
Future value = $100
Present value = $103
NPER = 25 × 2 = 50
PMT = $100 × 9% ÷ 2 = $4.5
The formula is presented below:
= -RATE(NPER;PMT;PV;FV;TYPE)
After applying the above formula, the rate is 4.3518%
Yearly rate is
= 4.3518% ×2
= 8.704%

The y-intercept is the y-value when x = 0. It is also when the graph crosses the y-axis.
Step-by-Step Explanation:
According the the graph given, the graph crosses the y-axis at 2. Therefore, when x = 0, y = 2, and we have our y-int.
