Solved Example

Q. Ms. Chapman wants to take her scout troop to Neon Nights roller rink. The employee she spoke to ahead of time said the total cost for all

9

people in the group would be

\$81

. This includes an entrance ticket and a

\$3

skate rental fee for each person.

\newline

Which equation can you use to find

t

, the cost of each entrance ticket?

\newline

Choices:

\newline

(A)

9(t + 3) = 81

\newline

(B)

3(t + 9) = 81

\newline

(C)

3t + 9 = 81

\newline

(D)

9t + 3 = 81

\newline

How much does each entrance ticket cost?

\newline

____

\$

Solution:

Identify Cost Components: Identify the total cost and components of the cost for each person. Each person pays for an entrance ticket $t$ and a skate rental fee of $3\$$ . The total cost for $9$ people is $81\$$ .
Set Up Equation: Set up the equation to represent the total cost. $\newline$ The total cost for one person is the ticket price plus the skate rental, so for one person it's $t + 3$ $\$$ . For $9$ people, it would be $9$ times $(t + 3$ $\$$ ), which gives the equation $9(t + 3) = 81$ .
Solve for t: Solve the equation for t. $\newline$ First, divide both sides of the equation by $9$ to isolate the term with $t$ : $\newline$ $9(t + 3) = 81$ $\newline$ $(t + 3) = \frac{81}{9}$ $\newline$ $t + 3 = 9$ $\newline$ Next, subtract $3$ from both sides to solve for $t$ : $\newline$ $t + 3 - 3 = 9 - 3$ $\newline$ $t = 6$
