20 represents the total number of tickets Kate purchased.
4 represents the number of tickets required to ride each ride.
r represents the number of rides Kate has already ridden.
(5-r) represents the number of rides Kate has not ridden yet.
The subtraction (20-4r) represents the number of tickets Kate has left after riding some rides.
The multiplication 4(5-r) represents the number of tickets Kate has left after riding some rides.
Each ride at the carnival requires 4 tickets to ride. Kate purchased 20 tickets and has already ridden some rides.
Kate writes the expression 20−4r and Brian writes the expression 4(5−r) to determine how many tickets Kate has left after riding some rides. Both expressions are correct.
Drag each description to explain each part of both expressions.
