Question

The number of people who attend a concert varies directly with the amount of money spent on advertising. If 790 tickets are sold when $2,547.75 is spent on advertising, how much money needs to be spent on advertisements to get a sellout crowd of 1500?

Answer 1

$4837.5

Explanation:

Given that,

790 tickets are sold when $2,547.75 is spent on advertising.

We need to find the money to be spent on advertisements to get a sellout crowd of 1500.

It is also mentioned that the number of people who attend a concert varies directly with the amount of money spent on advertising. Let money be x. So,

`(790)/(2547.75)=(1500)/(x)\\\\x=(2547.75* 1500)/(790)\\\\x=\$4837.5`

So, $4837.5 is spent on advertisements to get a sellout crowd of 1500
