Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
solve for r
Firstly we need to count how much did the employees earn after the raises:
4% from $41,000 =
= 4/100 * 41,000 =
= 4 * 410 =
= 1644
4,5% from 43,700 =
= 45/1000 * 43,700 =
= 45 * 43,7 =
= 1966,5
3% from 39,700 =
= 3/100 * 39,700 =
= 3 * 397 =
= 1191
Now we need to sum up all the raises:
1644 + 1966,5 + 1191 = 4801,5
So now we can clearly see that answer A ($4,802) is the closest one to the total of all three raises.
Answer:
3.2 feet.
Step-by-step explanation:
Since the total amount of water that was decreased is equal to 12.8, we would divide it by 4 to see how much it decreased in 1 week assuming it was constant. So, 12.8 divided by 4 is 3.2.
Answer:
y = 1/4x - 1 1/2
Step-by-step explanation:
(-6, -3) (2,-1)
y = -3 - (-1) = -2 = 1
x = -6 - 2 = -8 = 4
y = mx + b
-1 = 1/4(2) + b
-1 = 1/2 + b
-1/2 -1/2
-1 1/2 = b
y = 1/4x - 1 1/2
The final equation is y equals one fourth x minus one and one half.
