Dance Project By Warren Barge, and Zarius Buharivala
We will need $74.87 to attend the 7th grade dance.
$41.97 for the outfit.
$10.00 for the ticket to the dance.
$22.90 for the meal.
If our parents give us $75 it will be enough to cover the total cost of going to the dance, because we only need $74.87. We will have $00.13 left over: $75.00 - $74.87 = $00.13.
The increase in price from $10 for buying a ticket in advance, to $15 for buying a ticket at the door is a 50% increase.
We have to pay back our parents $75 plus a 5% interest rate. We will need to pay them back a total of $78.75: $75 x 105 = $78.75.
