I am assuming that the cost of an oil change already includes the mark-up.
So, 18 is 175%. 18 ÷ 1.75 = 10.29 is the original cost.
10.29 * 3/4 = 30.87/4 = 7.71 mark-up
10.29 + 7.71 = 18
Or if 18 is the basis of the mark-up, then,
18 * 3/4 = 54/4 = 13.50 mark-up
18 + 13.50 = 31.50 new cost of an oil change
Answer:
0.410714
Step-by-step explanation:
Dividend ÷ Divisor = Quotient
P = g - 50
The profit in this equation, p, is similar to the y value and the g in this equation is equal to the x value. Because the profit per glass sold is one, you can just leave it out end up with g - 50 because you are deducting your profit from your expense.
Answer:
-0.8 (A) -2.25 (B) -2 (C) (Look at explanation to see answers for first bubbles.)
Step-by-step explanation:
A:
1.4 - 2.2 = -0.8
B:
-0.75 - 1.5 = -2.25
C:
-0.2 - 1.8 = -2
Answer:
a=10, c=1.4
Step-by-step explanation:
so the ratio of the side with the length 5 to the side <em>a</em> is 1:2(or we could say a to 2a). Because of this we now multiply 2 to 5 to get a=10(because it is a 1 to 2 ratio).The relation between the side worth 2 and the side <em>c</em> is a√2 to a. so we divide √2 from 2 to get √2 and this number in decimal form is 1.41421356237....., so rounded to the nearest tenth is 1.4(because 1 rounds down)
