A pound of oranges cost x dollar => A pound of pears cost x+3 dollar

We have: 8x+4(x+3)=30 => 12x=30-12=18 =>x=1.5

5 pounds of pears cost: 5(x+3)=5(1.5+3)=5*4.5= 22.5 (dollar)

NNADVOKAT [17]

Statement 1 : Gail bought a $45 sweater at 1/3 off.

<u>Discount in Sweater Purchase:</u>

$\frac{1}{3} \; of \; 45 = \frac{1}{3} \times 45 \; = \;\frac{45}{3} =\$15$

Statement 2: Gail can use her 12% employee discount once a week and used her discount on the suit priced at $140.

Discount in Suit Purchase:

$12\% \; of \; 140 =\frac{12}{100} \times 140 = 0.12 \times 140 = \$16.8$

Conclusion:

<u>Discount in Suit Purchase ($16.8) is greater than Discount in Sweater Purchase ($15)</u>

How do i make a table of values for each function rule and then graph the function for these examples:

$\bf \begin{array}{ccllll}
y=1.5x-3\\
\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\\

x&y\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
-3&1.5(-3)-3\\
-2&1.5(-2)-3\\
-1&1.5(-1)-3\\
0&1.5(0)-3\\
1&1.5(1)-3\\
...&...
\end{array}$ $\bf \begin{array}{ccllll}
y=-x^2+4\\
\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\\

x&y\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
-3&-(-3)^2+4\\
-2&-(-2)^2+4\\
-1&-(-1)^2+4\\
0&-(0)^2+4\\
1&-(1)^2+4\\
...&...
\end{array}$

and so on, and then, you graph those x,y coordinates
