Solving other types of Word Problems
Using Bar Models
15% of the number of people who attended a concert arrived late. If 30 people arrived late, find the number of people who attended the concert.
From the above model, we see that
15% → 30 people
1% → 30 ÷ 15 = 2 people
100% → 100 × 2 = 200 people
200 people attended the concert.
Kathy earned $75 an hour. Andy earned 20% more money than Kathy. How much money did Andy earn in an hour?
100% + 20% = 120%
Andy’s earnings was 120% of Kathy’s earnings.
100% → $75
1% → $75 ÷ 100 = $0.75
120% → 120 × $0.75 = $90
Andy earned $90 an hour.
