:-) Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website! The store's "rate" of sales increase is ( sales increase ) / ( advertising spent )
Let = sales increase if the store spends $4500 on advertising
-------------
You can set up a ratio:
sales will increase $150,000 if $4,500 is spent on advertising
$4500 is 3 times as much as $1500 so sales must have increased 3 times as much
as they would have increased if they had spent only $1500, and 3 times $5000
is $15000.
