Original price = $30
Increase in 50% = 50% of $30 = 0.5 x 30 = $15
Price = 30 + 15 = $45
50% off
50% of $45 = 0.5 x 45 = $22.50
Price = 45 - 22.50 = $22.50
No, the sales price is not $30
Answer:the answer is 1
Step-by-step explanation:
2(4y-1)=6
Divid by 2 on both sides
4y-1=3
Add 1 to both sides
4y=4
Divid both sides by 4
Y=0
The answer should be -14/16
"Combinations" isn't really the right word, because a combination doesn't take order of elements into account, and the outcome of a race certainly does depend on order. "Permutations" would be the correct term.
If 4 students are competing, then the race has
4! = 4 • 3 • 2 • 1 = 24
possible outcomes.
