**The line graph below shows the number of visitors at the zoo from Monday to Saturday.****a) If each visitor paid $12 for a ticket, how much money was collected on weekdays?b) The number of visitors who visited the zoo on Sunday was 30% more than the number of visitors on Friday. What is the difference in the number of visitors between Saturday and Sunday?Solution**

Between “0” and “2000” on the vertical scale, there are 8 divisions.

8 divisions ----- 2000 (visitors)

1 division ----- 2000 divided 8 = 250 (visitors)

Data from graph above

(Mon) 2000 + 1 division ----- 2000 + 250 = 2250

(Tue) 2000 + 4 divisions ----- 2000 + 1000 = 3000

(Wed) 2000 + 2 divisions ----- 2500

(Thu) 2000 + 4 divisions ----- 3000

(Fri) 4000 + 3 divisions ----- 4750

(Sat) 6000 + 5 divisions ----- 7250

Total no. of visitors (Mon to Fri) ----- 15 500 visitors

a)

15 500 x $12 = $186 000

**Answer: The amount collected was $186 000**

b)

(Fri) 100% ----- 4750 (visitors)

(Sun) 130% ----- 130% x 4750 = 6175 (visitors)

Sat – Sun ----- 7250 – 6175 = 1075

**Answer: The difference in number of visitors is 1075.**
