Question

Sean is learning to scuba dive. The equation D = 20L + 15 represents the depth he can dive in feet, D, based on the number of lessons he has had, L. How deep can Sean dive after he takes 13 lessons?   

Answer 1

Answer:

Sean can dive 275 feet after he takes 13 lessons.

Step-by-step explanation:

Since L means the number of lessons taken, we will have:

D = 20*13 + 15

D = 260 +15

D = 275
