Oscar and Julie Ashton are celebrating their 15th anniversary by having a reception at a local reception hall. They have budgeted $2,000 for their reception. If the reception hall charges a $90 cleanup fee plus $31 per​ person, find the greatest number of people that they may invite and still stay within their budget.
first you take 2,000 and subtract the cleanup fee, you get  1910  then you divide that by 31 and get 61.61 but you cant invite half a person so they can invite 61 people in total.
