Answer:
-114
Step-by-step explanation:
Okay, to work out the original price, all you have to do is get the sale price ($146.54) and then divide it by 1 - 0.[whatever the percentage is]. In this case, the percentage is 15%, so you do 1 - 0.15 = 0.85.
So to work out the original price, you do:
146.54 ÷ 0.85 = $172.40
The original price is $172.40. :)
Answer:
Thus, n = 4 is the solution.
Step-by-step explanation:
1. perform the indicated multiplication, obtaining 3n + 24 = 36
2. Subtract 24 from both sides: 3n = 12
3. Solve this result for n: n = 12/3. Thus, n = 4 is the solution.
