Solution
Make numerators the same
35% staff = 35100 staff = 720 staff
70% visitors = 70100 visitors = 710 visitors
720 staff = 710 visitors
staff = 20 u
visitors = 10 u
Total units = 20 u + 10 u = 30 u
Difference in units = 20 u - 10 u = 10 u
30 u = 600
1 u = 600 ÷ 30 = 20
10 u = 10 x 20 = 200
Answer: 200
