Question

A boat costs $x$ dollars, and this cost is to be shared equally by a group of people. In terms of $x$, how many dollars less will each person contribute if there are $4$ people in the group instead of $3$?

• A. $\frac{x}{12}$
• B. $\frac{x}{4}$
• C. $\frac{x}{3}$
• D. $\frac{7x}{12}$
• E. $7x$

Answer 1

The correct option is A $\frac{x}{12}$

If there are three people each pays $\frac{x}{3}$.

If there are four people each pays $\frac{x}{4}$

The difference =$\frac{x}{3}-\frac{x}{4}=\frac{4x-3x}{12}=\frac{x}{12}$
