Answer:
The of tax is $ 2812.50
Step-by-step explanation:
Given that Mary's salary is $x per year, then applying the 15% flat tax rate will give the amount paid for tax as;
15/100 *x =0.15 x -----equation (i)
After reforms , Mary still pays a tax similar to the original system. This means the amount of Mary's salary is above $7500.
Mary's amount above is the flat rate of $7500 is ;
$(x-7500)
Applying the 25% tax will give;
25/100 ( x-7500)
0.25(x-7500)
0.25x -1875 --------equation (ii)
Equating the two equations
0.15x = 0.25x - 1875
collect like terms
1875=0.25x-0.15
1875 =0.10x
Divide both sides by 0.10 to get x
1875/0.10 = 0.10x/0.10
18750 = x
The amount of Mary's salary is $18750
The amount of tax she pays is;
0.15 * 18750 =$ 2812.50

Step-by-step explanation:
Answer:
<em>16.5 gallons per minute.</em>
Step-by-step explanation:
The given table is:
We are given this linear function in the form of table.
Let 't' be the time and W(t) be the function with which the gallons of water are changing with time.
We can use slope intercept form to find the equation.
Slope of a function:
This slope is the constant of proportionality.
i.e. the rate at which the number of gallons are changing per minute.
So, the answer is <em>16.5 gallons per minute.</em>
