Answer:
c) Percentages
Step-by-step explanation:
Percentages can be used to compare changes from one period to another.
In calculating a percentage change, either a percentage increase or percentage decrease, we must have both the new and old measurement of the specific quantity.
For example, let's find percentage increase of the number of students that joined a book club using the parameters below;
Original number of students = 32
New number of students = 36
We will calculate the increase using;
Substituting the values, we have;
Increase = 36 - 32 = 4
Percentage increase = 12.5%
Therefore, the number of students in the school club increased by 12.5%.
Answer:
For #1 the answer is City C
Step-by-step explanation:
To find the value of anything with a sales tax simply multiply the cost by the tax.
$30 * 2.9%
$30 * .029
$0.87
Now that we have the sales tax, add it to the original cost.
$30 + $0.87 = $30.87
You can do this for each of the sales tax problems. Then compare the answers.
M/k=x
(m)m/k=x(m)
k=xm
Because you are diving one the side where m/k, you need to multiply m to both sides to get rid of it on one. Therefore, you are left with K=XM
