Answer:
original price =148.57
Step-by-step explanation:
The original price * discount is the markdown
original price - discount = sale price
original price - original price * discount = sale price
Factor out the original price
original price (1-discount) = sale price
We know the discount is 65% and the sale price is 52
original price (1-.65) = 52
original price (.35) = 52
Divide by .35 on each side
original price (.35)/.35 = 52/.35
original price =148.57
Answer:
- The probability that the locker code begins with a prime number is 40%.
- The probability that the last digit of the locker code is an odd number is 40%
Step-by-step explanation:
- Prime numbers are the numbers that only divide with 1 or itself. So in this case it is 5 and 7.
The possible combinations are
1*4*3 (with 5) + 1*4*3(with 7) = 24
Total combinations are 5*4*3=60
(24/60)*100 = 40 %
2. Odd numbers are those which don't divide with 2. So in this case it is 6 and 8.
The possible combinations are
1*4*3 (with 6) + 1*4*3(with 8) = 24
Total combinations are 5*4*3=60
(24/60)*100 = 40 %
Simple not rlky but I think it's the second to last one
The first term is 7 because they both can be divided by 7.
