Buddy and bubbles are two of Santa's elves. Buddy can make 15 toys per hour while Bubbles can make 12 toys per hour. Write two expressions that could show the combined number of toys per hour that buddy and bubbles could make if they work the same amount of hours.

y=27x

Step-by-step explanation:

If Buddy makes 15 toys per hour we can use the expression [15x=y] (let x be # of hours worked). If Bubbles makes 12 toys per hour we can use the expression [12x=y]. To find out the number of toys they make together we can just find the total number of toys they make in an hour. (Combine the 2 equations).

15x+12x=y

27x=y
