Answer: the correct equation : [tex]\dfrac{3}{20}x=9[/tex]
The value of x= $60
Step-by-step explanation:
Let the total cost of the food be x .
Given that , Tram left a tip of $9, which was [tex]\dfrac{3}{20}[/tex] of the total cost of the food.
According to this statement , we have
[tex]\dfrac{3}{20}x=9[/tex]
Multiply 20 on both sides , we get
[tex]\dfrac{3}{20}x\times 20=9\times20[/tex]
[tex]\Rightarrow\ 3x=180[/tex]
Divide both sides by 3 , we get
[tex]x=60[/tex]
i.e. the total cost of the food = $60
Thus , the correct equation : [tex]\dfrac{3}{20}x=9[/tex]
The value of x= $60, where x is the total cost of the food.
