Question

Dante is saving money to buy a game. So far he has saved $20, which is four-fiths of the total cost of the game. How much does the game cosх$?

Answer 1

Money saved = $20

According to the statement we can establish the following equation

`20=(4)/(5)X`

where X is the total cost of the game

now let's find X

`\begin{gathered} (4)/(5)X=20 \\ 5\cdot(4)/(5)X=20\cdot\: 5 \\ 4X=100 \\ (4X)/(4)=(100)/(4) \\ X=25 \end{gathered}`

Therefore the total cost of the videogame is $25
