Answer:
y = ac / (a - b - c)
Step-by-step explanation:
y(a - b) = c(y + a)
Distribute
ay - by = cy + ac
Subtract cy from both sides
ay - by - cy = ac
Factor out y
y(a - b - c) = ac
Divide both sides by (a - b - c)
y = ac / (a - b - c)

11. discount is 7.20 dollars, sale price is 41.80
12. discount is 37.50. sale price is 112.50
13. discount is 590. sale price is 870
14. discount is 42. sales price is 42
15. discount is 32.50. sales price is 292.50
16. discount is 29.75. sales price is 56.25
17. The similarities is that there's a difference in the original price, usually in a percentage. The difference is that a markup is a increase whereas a discount is a decrease
Answer:
I'm here! This Problem is easy :) The answer is 4
Step-by-step explanation:
2x+10=5x−2
<em>Subtract </em>5x from both sides
2x+10−5x=−2
<em>Combine</em> 2x and −5x to get −3x.
−3x+10=−2
Subtract 10 from <em>both sides.</em>
−3x=−12
<em>Divide</em> both sides by −3.
Divide −12 by −3 to get 4.
x = 4 (D)
This is an increase of 3 yards.
