Answer:
Each game cost Robert $9.99.
Explanation:
To solve this problem, we are first asked to write an expression. We know that Robert bought a total of 20 games and that he spent $199.80. If we multiply the number of games Robert bought (20) by the price per game (what we are trying to figure out, represented by the variable x in this case), then we should get the total amount of money Robert spent. This is modeled below:
20x = 199.80
This equation will help us solve the problem. To solve, we should divide both sides by 20 to cancel out the 20 on the left side of the equation and isolate the variable x.
20x/20 = 199.80/20
x = 199.80/20
Therefore, the expression that represents how much each game costs is 199.80/20.
We can solve this by simply dividing the numerator by the denominator, leaving us with:
x = $9.99
This tells us that each game Robert bought cost $9.99.
Hope this helps!
