Answer:
Therefore there revenue was $540,000.
Step-by-step explanation:
Let their total revenue last year be x
so
35% of x = $72,9000 - x
or, 35/100 × x = 729000 - x
or, 7x/20 = 729000-x
or, 7x = 20(729000-x)
or, 7x = 1458000- 20x
or, 7x + 20x = 14580000
or, 27x = 14580000
or, x = 14580000/27
so, x = $540,000

He Delivered 10 newspapers on Flinders Street, hence:
He Delivered 6 newspapers on Collins Street, hence:
He Picked up 20 newspapers from the newsagent and Delivered 15 newspapers on Lonsdale Street, hence:
- = x - 16 + 20 - 15 = x - 11

x - 11 = 8
x = 20
Tom started with 20 newspapers on the morning and returned with 8 newspaper.
