There are 4 seats in each row of a bus except the last row, which has 5 seats. The total number of seats can be written as 5 + r x 4. Determine the number of seats in a bus for each value of r.
What are the values of r?
To determine the number of seats in a bus for each value of r, we need to substitute the values of r into the given equation and calculate the result.
The equation to calculate the total number of seats in a bus is: Total seats = 5 + r x 4
Let's substitute different values of r into the equation and solve for the number of seats:
For r = 0:
Total seats = 5 + 0 x 4 = 5 + 0 = 5
For r = 1:
Total seats = 5 + 1 x 4 = 5 + 4 = 9
For r = 2:
Total seats = 5 + 2 x 4 = 5 + 8 = 13
For r = 3:
Total seats = 5 + 3 x 4 = 5 + 12 = 17
For r = 4:
Total seats = 5 + 4 x 4 = 5 + 16 = 21
For any value of r, we can use the equation Total seats = 5 + r x 4 to calculate the number of seats in a bus.
