One Friday night, two large groups of people called Weston Taxi Service. The first group requested 2 sedans and 1 minivan, which can seat a total of 14 people.

Sedan: 4 passengers

Minivan: 6 passengers

Step-by-step explanation:

We can write the following system of equations:

$$\begin{cases}2s+1m=14 \\2s+2m=20\end{cases}$$, where $$s$$ represents the number of people a sedan can seat and $$m$$ represents the number of people a minivan can seat.

Subtracting the first equation from the second, we have:

$$2s+2m-(2s+1m)=20-14,\\\\m=6$$

Now plug in $$m=6$$ in any of the equations to solve for $$s$$:

$$2s+1(6)=14, \\2s=8, \\s=4$$

Verify that the solution pair $$(4, 6)$$ works:

$$2(4)+1(6)=14\: \checkmark \\2(4)+2(6)=20 \: \checkmark$$

Therefore, a sedan can hold 4 passengers and a minivan can hold 6 passengers.
