Question 404880
The different amounts of donation is due to the varying value of the bursaries.
To find the minimum amount that the Lodge donated, assume that the bursaries are worth the least possible, or $250 each.
$15,000+50(250)    $15,000 plus the value of the bursaries
$15,000+$12,500
$27,500
 
To find the maximum amount that the Lodge donated, assume that the bursaries are worth the most possible, or $350 each.
$15,000+$50(350)    $15,000 plus the value of the bursaries
$15,000+$17,500
$32,500
 
Thus the Lodge could have donated a minimum of $27,500 and a maximum of $32,500 :)
