B. what is the cost of the haircut
C. calculate the total cost of the haircut, including the tip
D.If you only wanted to know the tip amount, how would you change the process you used in part c to calculate the total cost
Answer:
Sure! Here are the answers:
A. Jeremy paid 100% + 15% = **115%** of the cost to the barber, including the tip.
B. Let's say the cost of the haircut is x dollars. Then, Jeremy paid a tip of 15% of x which is 0.15x dollars. Therefore, the cost of the haircut is x + 0.15x = **1.15x** dollars.
C. The total cost of the haircut, including the tip is 115% of the cost of the haircut. So, if the cost of the haircut is x dollars, then the total cost is 115% of x which is 1.15x dollars.
D. If you only wanted to know the tip amount, you would calculate 15% of the cost of the haircut which is 0.15 times x or **0.15x** dollars.
I hope this helps!
Step-by-step explanation:
Answer:
The number of cans of paint he used for each wall is cans
Step-by-step explanation:
Here we are told that Sam used 17 cans of paint to paint 6 walls
The correct way to find out how many cans of paint he used to paint each wall is as follows
Number of walls 17 cans of paint can paint = 6 Walls, we therefore divide both side of the equation by 6 so that the number of walls painted will be 1 as follows
6 Walls = Number of walls 17 cans of paint can paint
6/6 Walls = Number of walls 17/6 cans of paint can paint
∴ 1 Walls = Number of walls 17/6 cans of paint can paint or
∴ 1 Wall = Number of walls cans of paint can paint
Which gives;
Number of walls cans of paint can paint = 1 Wall or
The number of cans of paint he used for each wall = cans.
