Let us assume the total number of bowls of cereal that Nathan has eaten in a year = x
With each bowl of cereal, Nathan has 1/18 gallon of Milk.
In total the number of gallons of mulk in a year = 8 gallons,
Therefore, we frame the equation as shown below to calculate "x"
1/18 * x = 8
x = 18*8 = 144
Number of bowls of cereal Nathan ate in a year = 144 bowls

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

x% of 75.5 is 81.54
x% * 75.5 = 81.54
x/100 * 75.5 = 81.54
x = 81.54 * 100 / 75.5
x = 108%
Result: 108% of 75.5 is 81.54.
The number 81.54 is 107.99% percentage of 75.5
We have,
To find what percent of 75.5 is 81.54, we can use the following formula:
(81.54 / 75.5) * 100
Step 1: Divide 81.54 by 75.5:
81.54 / 75.5 ≈ 1.0799
Step 2: Multiply the result by 100 to convert it to a percentage:
1.0799 * 100 ≈ 107.99
Therefore, 81.54 is approximately 107.99% of 75.5.
To explain it further, if we consider 75.5 as the whole or 100%, then 81.54 is approximately 107.99% of that whole value.
Thus,
In other words, 81.54 represents about 107.99% of 75.5.

John: 1 b/15s * 3600 s/h = 240 b/h
Jamie: 1 b/20s * 3600 s/h = 180 b/h
Jake: 180 b/h
Then sum the rates to obtain the total rate
Total ballons per hour: 240 b/h + 180 b/h + 180b/h = 600 b/h
If it passes x hours the number of ballons inflated is 600*x
The number of ballon defective are 600*x/80
The number of ballons effectiveley inflated = 600x -600x/80 = 600x - 7.5x = 592.5x.
