Real-Life Math -- Solution
You are a university president organizing a fund-raising dinner
to earn money to do renovations on the school library. You calculate how much
you could earn from the dinner:
Costs = hall rental + catering +
guest speaker's fee
Costs = $3,000 + $6,000 + $2,500
Costs =
$11,500
143 individual tickets at a cost of $150 each:
143
x $150 = $21,450
240 couples' tickets (that is, tickets for
480 people) at a cost of $275 for 2 tickets:
240 x $275 = $66,000
50
tables of 10 at a cost of $1,000:
50 x $1,000 = $50,000
Total
ticket sales = $21,450 + $66,000 + $50,000
Total ticket sales = $137,450
Sales
minus costs = $137,450 - $11,500
Sales minus costs = $125,950
You
will make a profit of $125,950 on the dinner. This won't be enough to
complete the renovations, but it's a good start.
