Answer:
15
Step-by-step explanation:
When a number x varies directly to another number y, then x/y is a constant c. In this scenario, x = 12 and y = 5, so x/y is 2.4. If x = 36, x/y still should be 2.4, so 36/y = 2.4. You multiple both sides by y to get 36 = 2.4y, and divide by 2.4 to get 15 = y or y = 15.
