Question

Tram left a tip of $9, which was StartFraction 3 over 20 EndFraction of the total cost of the food. Which shows the correct equation and value of x, the total cost of the food? StartFraction 3 over 20 EndFraction x = 9; x = $1.35 StartFraction 3 over 20 EndFraction x = 9; x = $60 StartFraction 3 over 20 EndFraction = StartFraction x over 9 EndFraction; x = $1.35 StartFraction 3 over 20 EndFraction = StartFraction x over 9 EndFraction; x = $60

Answer 1

Answer:

Option B.

Step-by-step explanation:

It is given that Tram left a tip of $9, which was $\dfrac{3}{20}$ of the total cost of the food.  

Let x be the total cost of the food. So, amount of tip is

$Tip=\dfrac{3}{20}x$

Tram left a tip of $9.

$\dfrac{3}{20}x=9$

Multiply both sides by 20.

$3x=180$

Divide both sides by 3.

$x=60$

So, total cost of food is $60.

Therefore, the correct option is B.
