PLEASE HELP ME :) I DID THIS PROBLEM 7 TIMES AND ITS STILL WRONG PLEASE
fiasKO [112]

Answer: $95450

Step-by-step explanation:

We obviously want to look in the 3rd column.

Income that can be taxed is within interval for 33%, so (0.33)(315000) = $103950.

Subtract the tax credit, and we get $103950 - $8500 = $95450.

Answer:

<em>16.5 gallons per minute.</em>

Step-by-step explanation:

The given table is:

\begin{center}\begin{tabular}{ c c } Time(minutes) & Water(gallons) \\ 1 & 16.50  \\  1.5 & 24.75  \\   2 & 33   \\\end{tabular}\end{center}

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.

y=mx+c

Slope of a function:

m=\dfrac{y_2-y_1}{x_2-x_1}

x_2 = 1.5\\x_1 = 1\\y_2 = 24.75\\y_1 = 16.50

m=\dfrac{24.75-16.50}{1.5-1}\\\Rightarrow m =16.5

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>

cross multiply

2x - 4 = 4 × 5

2x - 4 =20

collect like terms (CLT)

2x = 20 + 4

2x=24

divide both sides by 2
