Answer:
B. $715
Step-by-step explanation:
By multiplying your starting value, in this case $550, and your (simple) interest, 6%, or by 1.06 as 0.06 being your interest value and the 1.00 accommodating your starting value you will multiply, $550 × 1.06 = $583. Repeat these steps for however many years you are account for, in this case, five years. Giving you a total of $715

Answer:
b. Subtracting the base period amount from the analysis period amount, dividing the result by the base period amount, then multiplying that amount by 100%
Step-by-step explanation:
A percentage change can be computed from ...
((new amount) -(old amount))/(old amount) × 100%
This best matches the description of choice B.
_____
<em>Comment on the answer</em>
The formula offered in the question will show the "percent change" from 100 to 103 as 3. It is not 3; rather, it is 3%. The final multiplication must be by 100% in order to arrive at the proper number.
A, rotated then reflected
Answer:
r = 54 miles per hour
Step-by-step explanation:
Since we have been given the values for two of the unknowns, we can substitute them into the equation to find the third.
d = 405
t = 7.5
d = rt
405 = r (7.5)
405=7.5r
Now to find r, we need to get it by itself on one side so we have r = ...
We can do this by dividing 7.5 from both sides of the equation as this will cancel out the 7.5, leaving us with the r value, and everything you do to one side of an equation must also be done to the other side.
405/7.5=7.5r/7.5
54=r
The unknown value 'r' = 54
Since 'r' stands for 'rate', the units given must be appropriate for speed. As the distance was given in miles, and the time in hours, the unit for 'r' must be miles/hour. Therefore r=54miles/hour.
Hope this helped!
