Question

The Suarez family paid $\$15.75$ for 3 movie tickets. How much would they have paid for 12 tickets?

Answer 1

Hint: To solve this question we will use the unitary method. First we will calculate the price of one movie ticket by dividing the total cost by 3. Then we will multiply the price of one ticket by 12 to get the total cost of 12 tickets.

Complete step by step answer:
We have been given that the Suarez family paid $\$15.75$ for 3 movie tickets.
We have to calculate the amount they have paid for 12 tickets.
Now, first we need to calculate the price of one ticket.
For this we divide the $\$15.75$ by 3 we get
$\Rightarrow \dfrac{\$15.75}{3}$
Now, simplifying the above equation we get
$\Rightarrow \$5.25$
Now, to calculate the total cost of 12 tickets we multiply the price of one ticket by 12. Then we will get
$\Rightarrow \$5.25\times12$
Now, simplifying the above equation we get
$\Rightarrow \$63.0$

So we get the total cost of 12 tickets as $\$63.0$.

Note: The unitary method is a technique for solving a problem by first finding the value of a single unit then finding the required value by multiplying the value of a single unit. This method is used to find the value of a unit from the value of a multiple. Unitary method can be based on direct variation or inverse variation. Avoid calculation mistakes as a single mistake leads to the incorrect answer.
