Question 1172649
<br>
The cost of the caterer per person is $2.25; and the total cost per person is to be kept between $2.75 and $3.25.<br>
That means the cost per person of the band has to be between $2.75-$2.25 = $0.50 and $3.25-$2.25 = $1.00.<br>
Since the cost of the band is $750, the number of people that must attend is between {{{750/1 = 750}}} and {{{750/(.5) = 1500}}}<br>
