Answer:
$9.47
Step-by-step explanation:
Add all her purchases together
97.62 + 22.95 + 14.78 = 135.35
The total tax is 6.5% sales tax, and 0.5% country tax
6.5% + 0.5% = 7%
Multiply the total amount spent by the total tax
Remembering that you need to convert the 7% into an integer, by simply diving by 100 first
135.35 * 0.07 = 9.47
So for this you need to find 15% of 60. There are a few ways to do this but I prefer to do it like this.
First, find 10% of 60. This can be found by dividing 60 by 10, because 100%/10% is 10.
This gives 10%=6
5% is half of 10%, so divide your answer for 10% (6), by 2.
This gives 5%=3
We needed 15%, so we add our 10% and 5% together, to get 9.
15% of 60 is 9, meaning there are 9 puppies.
Hope this helps!
Answer:
1.2%
Step-by-step explanation:
We know that for every 500 computers, 6 are defective. So, to know what percentage of computers are defective on average, we can do a rule of three:
500 computers -> 6 defective
100 computers -> X defective
500/100 = 6/X
X = 100 * 6 / 500 = 1.2
So, in average, for every 100 computers, 1.2 are defective, so the percentage is 1.2% (1.2 for every 100)
The correct answer is b. -14
