Answer:
Cost in dollars and cents for each video game = $23.98
Step-by-step explanation:
Total amount Marshall paid for four video games = $100
Total change given to Marshall = $4.08
Actual cost of the video games = Total amount Marshall paid for four video games - Total change given to Marshall
= $100 - $4.08
= $95.92
Total number of videos games bought = 4
What is the cost in dollars and cents for each video game
Cost of each video game = Actual cost of the video games / Total number of videos games bought
= $95.92 / 4
= $23.98
Cost in dollars and cents for each video game = $23.98
23 dollars .98 cent
