Question

The Semmes library will raise funds by selling bumper stickers. The equation p=2s-20 is used to calculate the profit the library earns (p) if a certain number of bumper stickers (s) is sold. which table has values that correspond to the equation.

Answer 1

Explanation

Step 1

the function we have is:

$p=2s-20$

where p is the profit( dependent variable)

and s is the stickers sold ( independent variable)

so, in order to figure out this, we can simply make the table, so

Step 1

make the table, replace the input value(s) in the equation to get the output value( P)

hence

$\begin{gathered} p=2s-20 \\ \text{for s=1} \\ p=2(1)-20 \\ p=2-20 \\ p=-18 \\ \text{hence, we will have the pair ordered ( 1},-18) \end{gathered}$

after checking the options, we can conclude the last tables 2 and 4 are not the solution because for the same

$\begin{gathered} \text{table 2, ( 1,18)} \\ \text{table}4,\text{ (1,2)} \end{gathered}$

Step 2

now, when the input is 10

so

$\begin{gathered} p=2s-20 \\ p=2(10)-20 \\ p=0 \\ so,\text{ the ordered pair is (10,0)} \end{gathered}$

therefore, we can conclude that the table is the solution, because it has this orderede pair

$\begin{gathered} \text{fucntion (10,0)} \\ \text{table}1(10,0) \end{gathered}$

we can discard table 4 as well,

so, the answer is table 1

I hope this helps you
