Question

ari spent 35.80 for 4 posters . If the price of each poster was the same . what was the price of 1 poster

Answer 1

You have to determine the price for each poster, knowing that 4 of them cost $35.80 and that they cost the same. To calculate the price per poster you can divide the total cost by the number of posters purchased:

`(35.80)/(4)=8.95`

You can also use the cross multiplication method to determine the price per poster:

4posters → $35.80

1poster → $x

Both expressions have to be at the same proportion so that

`\begin{gathered} (35.80)/(4)=(x)/(1) \\ x=(35.80)/(4) \\ x=8.95 \end{gathered}`

Using either method we arrived at the same conclusion, each poster costs $8.95
