Answer: D
Step-by-step explanation: The rate at which the pool is filled is 1 gallon per 9 minutes. If you divide all the numbers of minutes in the left side of the table with the number of gallons on the right you get 9 minutes per gallon for each of them so they follow the rate.
Let us assume last year the price of the item = $x.
After increase in price by 15% the new price = x + 15% of x = x+ 0.15x = 1.15x.
There is a 25% discount for employee.
25% of 1.15x = 0.25 × 1.15x = 0.2875 x.
Price after discount = 1.15x - 0.2875 x = 0.8625x.
The employee pays $172.50.
Therefore,
0.8625x = 172.50.
Dividing both sides by 0.08625.

<h3>x=200.</h3><h3>Therefore, last year the price was $200.</h3>
Answer: 7/6 or 1 and 1/6
Step-by-step explanation:
2 1
+
3 2
you have to make them have the same denominators(the number on the bottom of a fraction)
2/3--> 4/6
1/2---> 3/6
4/6+3/6=7/6 or 1 and 1/6
First work out the difference:
75-40 = 30
30/75 * 100 = 40% decrease.
