Answer:
Point A (2.5, 14)
Step-by-step explanation:
The function for the charging fee, y, would be the initial $2 plus $4/hour for the charging time, x. This can be written as:
y = 4x + 2
Technically, both points A and C would not fall on theis line.
A: 2.5*4 + 2 = 12, not 12
C: at x = 0, there the equation still returns a $2 initial fee. So this should be (0,2) according to the equation. But it also makes sense to state that if the charging station is not used, there would be no charge. So a better way of expressing the equation would be to state that:
y = 4x + 2 for x > 0
Conclusion: Point A (2.5, 14) would not fall on this line.
There are 12 months in a yr so 12/3=4 then 1/3x4=4/3 so 1ft and 1/3 erode each yr. C is the correct answer<span />
The amount of money she would have is $10,291.50.
The amount of money she would have to buy the gift is the sum of the amount deposited and the interest.
Simple interest is interest that only accrues on the amount of money deposited into the account.
The formula that can be used to determine simple interest is: principal x time x interest rate
Where:
- Principal = amount deposited = $10,000
- Time = 11/12
- Interest rate = 3.18%
$10,000 x 11/12 x 0.0318 = $291.50
$10,000 + $291.50 = $10,291.50
so let's say the equation is 250×2%x meaning the 250 is the y and 2% is the x but the so in simpler terms 2x but u need to put 2%x
Answer:
Option D.$8820
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
