It is estimated that 20 patrons will attend an event for every $100 spent in advertising. If tickets cost $40, how much can a promoter expect to increase sales if he spends $10,000 in advertising?

Explanation:
In working through a word problem like this, read it a few times to understand the scenario being presented, without paying too much attention to the numbers.....Something like....
"If a promoter spends some money on advertising he will attract more patrons."
Summarise the information in short sentences.
The promoter spends $10,000.
"For every $100 spent, 20 patrons are attracted"
"Tickets cost $40"
Now plan the calculations:
(This is our thinking, not necessarily written down)
1) How many $100 payments are there in $10,000?
2) Each payment brings 20 patrons.
3) Each patron buys a $40 ticket.
1)
2)
3)

income is $80,000

Expenditure
Income

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So if $10,000 is spent on advertising (expenditure) we have:
Multiply both sides by
