Question

Keiko is saving money to buy a game. So far she has saved $20, which is four-fifths of the total cost of the game. How much does the game cost?

Answer 1

To find out the total cost of the game, we can set up an equation based on the information given.

Let's assume the total cost of the game is represented by "x" dollars.

According to the problem, Keiko has saved $20, which is four-fifths of the total cost of the game. This can be written as:

4/5 * x = $20

To find the value of x, we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by the reciprocal of 4/5, which is 5/4.

(4/5 * x) * (5/4) = $20 * (5/4)

Simplifying the equation gives us:

x = $25

Therefore, the total cost of the game is $25.
