A) 2277 = 110% of number in 2013
b) Number in 2013 = 90% of year before, 2012
2277 = 110% of Number in 2103
2277 = (110/100) * Number in 2013
2277 * 100/110 = Number in 2013
2070 = Number in 2013
Number in 2013 is = 2070
b) Number in 2013 = 90% of year before, 2012
2070 = (90/100) * Number in 2012
2070 * 100/90 = Number in 2012
2300 = Number in 2012
Hence number in 2012 = 2300 student athletes.
Answer:
<h2>2. (0, -4)</h2>
Step-by-step explanation:

Answer:
Holly will still pay 86% of the original price.
Step-by-step explanation:
Given
- Holly gets 14% off a shirt, so
To determine
What percent of the original price will still pay.
All we need is to subtract the percentage of discount from 100.
i.e.
100 - Discount = 100 - 14 = 86%
The amount left over would be what remains of the original price after Holly gets 14 % off a shirt.
Thus, Holly will still pay 86% of the original price.
Answer:
19 : 25
Step-by-step explanation:
Answer:
Carter family = 25 hours
Davis family = 31 hours
Step-by-step explanation:
Let's say the number of hours the Carter family used their sprinkler is x and the number of hours the Davis family used their sprinkler for is y.
So combined:
x + y = 45 hours
and we are also told that:
40x + 15y = 1300 L
So we can do simultaneous equations to solve the problem.
With some rearranging, we can figure out that:
y= 45 - x
and by substituting that into the second equation:
40x + 15 (45 -x) = 40x + 675 - 15x = 1300L
25x = 1300 - 675
25x = 625
x = 25 = hours that the Carter family used their sprinkler
and we can substitute that back into the original equation to find how many hours the Davis family used their sprinkler so:
25 + y = 56
y = 31
The Davis family used their sprinkler for 31 hours whilst the Carter family used their sprinkler for 25 hours.
