The graph shows the number of audiences attended musical concert in the Esplanade theatre during a weekend.

(a) How many more audiences were there on Sunday than on Saturday?

(b) What was the total amount of money collected on Sunday if the ticket is \$9 for an adult and \$5 for a child?

Solution:

Total number of audiences = Adults + Children

From the Bar-chart,

The number of audiences on Saturday = 250 + 400 = 650

The number of audiences on Sunday = 300 + 450 = 750

There were 750 – 650 = 100 more audiences on Sunday than on Saturday.

From the Bar-chart,

The number of adult audiences on Sunday = 300

The money collected for adult audiences on Sunday = 300 × 9 = \$2700

The number of children audiences on Sunday = 450

The money collected for children audiences on Sunday = 450 × 5 = \$2250

The total money collected on Sunday = 2700 + 2250 = \$4950
