Marcos drove twice as far as Candice. Together, they drove 66 miles. Which equation can be used to find the number of miles Candice drove?

A) 3x = 66

B) 2x+1/2x=66

C) 3x = 66 + x

D) 3x=66-x

x = miles Candice drove

2x = miles Marcus drove

x + 2x = 66 = miles driven together
3x = 66

To find the number of miles Candice drove, we need to set up an equation based on the information given. Let's assume that Marcos drove x miles. Since Marcos drove twice as far as Candice, we can conclude that Candice drove x/2 miles.

We also know that the sum of their distances is 66 miles. So, the equation would be:

x + x/2 = 66

Simplifying this equation, we get:

2x + x = 66

Combining like terms, we have:

3x = 66

Therefore, the correct equation to find the number of miles Candice drove is:

A) 3x = 66
