Question

Kara bought $32$ movie tickets for $\$7200$. Find the first error that occurred while calculating the cost of 1 ticket.

• A. No error
• B. Step 1: Cost of one ticket $=\frac{\text{Total cost}}{\text{Number of tickets}}$
• C. Step 3: Cost of one ticket $=\frac{1}{7200}\times 32$
• D. Step 2: Cost of one ticket $=\frac{7200}{32}$

Answer 1

The correct option is C Step 3: Cost of one ticket $=\frac{1}{7200}\times 32$

The correct steps to calculate the cost of one ticket is as follows:

$\text{Cost of one ticket}=\frac{\text{Total cost}}{\text{Number of tickets}}$

$\text{Cost of one ticket}=\frac{7200}{32}$

$\text{Cost of one ticket}=7200\times \frac{1}{32}=\$225$

So, step $3$ is incorrect.
