Say that you buy 30 apples for $20, you take how many apples there are and divide it by how much they cost, they cost $1.5 per apples (looks like this, Unit/Rate)
Prime numbers are 2,3,5,7,11,13,17,19,23 that's 9 of them the other 16 are not prime (1,4,6,8,9,10,12,14,15,16,18,20,21,22,24,25)
so 16/25 or 64% is the probability of not getting a prime number
Answer:
$324
Step-by-step explanation:
Two ways to look at it:
Change 25 % to a decimal
$400 x .25= $100 is the discount
$400- $100= $300
Sales Tax: change 8% to a decimal
300 x .08= $24
Total cost is $324
or you can say you are paying 75% for the camera since it is discounted 25%
So change 75% to .75
$400 x .75=$300
Sales Tax: change 8% to a decimal
300 x .08= $24
Total cost is $324
