GarageBand

The local band has made it BIG TIME! ... because now they can now move their gig to a local bar. The bar charges a $20 starter fee and $2 for each person at the concert. The tickets are sold at a price of $5 and one of the mothers of the band members donated $5 to start off their income for the night. Time to find out if the band will gain or lose money!

POI (5,30)

Y=mx+b

5p+5=2p+20

5p-2p=20-5

3p=15

p=5

__________

C=5(5)+5

C=25+5

C=30

___________

C=2(5)+20

C=10+20

C=30


Therefore, the POI is 5,30. This is when the cost and expenses and income will be the same amount of money.

ENCORE... or the end!

In conclusion, the band's income weighed over their expenses. As long as there were tickets sold, the band did not lose any money. The band made $255 and lost $120. They had a total $135 left over after the expenses. Therefore, the expenses successfully paid using the income from the night. Bravo!
