Step-by-step explanation:
Okay, here's my best try.
Suppose you have a bill for $8.45
If you are asked to add, say, 8% tax, you must calculate 8 percent of 8.45 and then add it to 8.45.
Begin by converting 8% to decimals by dividing by 100.
8% is 0.08 in decimal form.
To calculate a percentage of a number, you multiply the decimal percent by the number; example:
8.45 is being multiplied by 0.08. The result is: 0.676. (this is the tax; however you have to round up to two decimal places: $0.68)
After finding the tax amount, if you are asked to add it to the bill, you have to add it to the original bill; in this case, $8.45
This would be: 0.68+8.45=9.13.
Therefore, the total bill after tax is for $9.13

With tips is the same thing, however, you can have 2 situations.
Situation 1: You are asked to calculate 15% tip of total bill.
In this situation, you can do the same we do to calculate tax.
Convert the percentage to decimal by dividing by 100.
and multiply it by the original bill.
. Rounding up, this would be $1.27 for tip.
If you were to add it to the original bill, simply sum.
The total bill after tips is for $9.72
Situation 2: You are asked to calculate 15% tip of the total bill with a tax of 8% included.
In this situation, you must first calculate the total bill with the tax added, like we did above; we got a bill for $9.13 (Tax included)
Then you can calculate 15% tip of this new bill that has tax included.
Convert
Multiply by the new bill (because this is the one that includes tax)
Round up.... $1.37 for tips.
If you are asked to give a total amount of money including tax and tips, add this to the bill.
9.13+1.37=10.50
This bill would be for $10.50
Answer:
Part (A): The required inequality is T < 35 or t >40.
Part (B): The correct option is C) Only x=7.
Part (C) |x+1|+5=2 has no solution; |4x+12|=0 has one solution; |3x|=9 has two solution.
Step-by-step explanation:
Consider the provided information.
Part (A)
Storing milk at temperatures colder than 35°F can affect its quality of taste. However, storing milk at temperatures warmer than 40°F is an unsafe food practice.
The union is written as A∪B or “A or B”.
The intersection of two sets is written as A∩B or “A and B”
We need to determine the inequalities represent the union of these improper storage.
That means we will use A∪B or “A or B”.
The improper storage temperatures is when temperature is less than 35°F or greater than 40°F.
Hence, the required inequality is T < 35 or t >40.
Part (B) 15| x-7|+4=10|x-7|+4
Solve the inequality as shown below:
Subtract 4 from both sides.
Subtract 10|x-7| from both sides
Hence, the correct option is C) Only x=7.
Part (C) Match the solution,
Subtract 2 from both sides.
Absolute value cannot be less than 0.
Hence, |x+1|+5=2 has no solution.
Hence, |4x+12|=0 has one solution.
Hence, |3x|=9 has two solution.
