I think u need to subtract both up and both down
Answer:
1/2
Step-by-step explanation:
42 is the answer
Explanation:
50% of 80 is half of 80 which is 40
Then you would add 40 with 5% of 40
What you would do then is 5% times 40 then you would change the 5% into a decimal which is 0.05 and multiply it by 40 , which would get u 2
Then you would add the price with tax
40+2 = 42
This is a permutation problem in which you are to arrange the objects and the order doesn't matter. You can easily calculate it using your scientific calculator. Just use the formula nPr, where n is the total number of objects taken r at a time.
PAYMENT = 7 letters => 7P5 = 2520
There are 2,520 ways
For butterfly, its quite tricky because there are two letters. Oder does matter here, since no matter which t comes first, that is still the same. So, this is what you do:
BUTTERFLY = 9 letters
9P5 ÷ 2! => since there are two same letters
15120 ÷ 2 = 7560
There are 7560 ways.
