The science center has 300 people in attendance on Tuesday. This is 150 percent of the attendance on Monday. 200 people were there in attendance on Monday.
Let the attendance on Monday be x.
Since the attendance on Tuesday is 150% of that of Monday's,
∴ Attendance on Tuesday = 150% of x = 1.5 × x
From the problem, attendance on Tuesday = 300.
∴ 1.5 × x = 300
⇒ x = 300 ÷ 1.5
⇒ x = 200.
So, the attendance on Monday = x = 200.
