It is either the Second or third one
Answer:
-n^2 - 5n + 24
Step-by-step explanation:
Let the number be n.
Then the sum of that number and 3 is n+3.
The difference of 8 and the number is 8 - n.
Then we get the expression (n + 3)(8 - n).
Performing the indicated multiplication, we get:
8n - n^2 + 24 - 3n, or
-n^2 - 5n + 24
Nothing more can be done, as this is not an equation, but rather an expression.

Any line can be graphed using two points. Select two
x
values, and plug them into the equation to find the corresponding
y
values.
Choose
0
to substitute in for
x
to find the ordered pair.
y
=
9
Choose
1
to substitute in for
x
to find the ordered pair.
y
=
12
Create a table of the
x
and
y
values.

to just find the tip amount, multiple 24 by .15 (since percents are just the number divided by 100) to get the answer (3.60) or for the total multiple the amount by 1.(whatever the percent is), or in this case 1.15 to get the answer (27.60)
