Mathematics

Answer:

4n = 24

Step-by-step explanation:

Given

Cars = 4

Empty = 3

Occupied = 21

Required

Determine an equation to find number of seats

Let the number of seats in each car be represented by n;

If 1\ car = n

Then:

4\ cars = 4 * n

4\ cars = 4 n

This implies that there are 4n total seats

Solving further:

Occupied\ Seats + Empty\ Seats = Total

Substitute values for the above parameters:

21 + 3 = 4n

24 = 4n

Reorder

4n = 24 ---- This equation can be used to solve for n
