The price of an item yesterday was 110. Today the price fell to 33 find the percentage decrease
Answers
The decrease as a fraction of the original amount is ( 77 / 110 ) .
As a decimal, 77/110 = 0.7 .
To change a decimal to a percent, move
the decimal point two places that way ==> .
0.7 ==> 70% .
33-x
X=30
100-30=70% is the answer

They are the commutative, associative, multiplicative identity and distributive properties.
Commutative property: For example 6 * 7 = 7 * 6;
Associative Property: For example (7 * 8) * 9 = 7 * (8 * 9);
Multiplicative Identity Property: For example 6 * 1 = 6 or, 1 * 6 = 6;
Distributive property: For example 6 * ( 7 + 8) = 6 * 7 + 6 * 8 or, ( 7 + 8) * 6 = 7 * 6 + 8 * 6.

In the aerobics classes of 4 will the cost for members and nonmember be the same.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
At a local fitness center, members pay an $8 membership fee and $4 for each aerobic class.
And, Nonmembers pay $6 for each aerobic class.
Now,
We can formulate;
For members, the cost = $8 + 4x
Where, x is the aerobic class.
For nonmembers;
The cost = 6x
We can equate both the equation, we get;
6x = 8 + 4x
Solve for x as;
6x - 4x = 8
2x = 8
x = 4
Thus, In the aerobics classes of 4 will the cost for members and nonmember be the same.

For every member lesson, they pay $4, so they will be represented as 4a
For every non member lesson, they pay $6, so they are 6a
Don't forget members have to pay $8 at the start, so they have to be 4a + 8
So
4a + 8 = 6a is our final equation
Move the 'a's to one side, by subtracting 4a from each side, giving you
8 = 2a
Divide by 2 to isolate a
4 = a
After 4 aerobics classes, the cost will be the same
