Question

Four times the sum of a number and 24 is at most 20.

Answer 1

4(x + 24) <= 20

Breaking it down grammatically:

Four times the SUM.

So the SUM is its own entity. What are we summing? "A number" and 24. So we call the sum (x + 24).

Then four times the sum is 4(x + 24).

This is AT MOST 20. So it is less than, or equal to, 20.
