Shakira played 3 full games because rounding off to 4 would increase the total.
Step-by-step explanation:
Given,
Rent of shoes = $3
Amount paid for each game = $4.75
Total paid by Shakira = $21
Let,
x be the number of games played by Shakira.
Amount paid for each game * Number of games + Rent of shoes = Total paid
[tex]4.75x+3=21\\4.75x=21-3\\4.75x=18[/tex]
Dividing both sides by 4.75
[tex]\frac{4.75x}{4.75}=\frac{18}{4.75}\\x=3.8[/tex]
Therefore,
Shakira played 3 full games because rounding off to 4 would increase the total.
