# Income VS Expenses of A Concert

## 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!

## Variables Used

C = Cost (\$)

p = number of people

## 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!
