Outfit Cost

The total cost for the outfit is $41.96 after the discount and tax. We found it by multiplying 30 by $56.55 then with that answer divided by 100, the answer was $16.96. That was the discount. Then we subtracted $16.96 from $56.55 and got $39.59. Next we multiplied 6 times $39.59 and with the answer divided 100 and got $2.37. That is tax, then we added that to $39.59 and got $41.96 for the total cost for the outfit.

Dinner Cost

The total cost of the dinner was $22.90 after tax and a tip. We found this by multiplying 6 by 18 then with the answer divided 100. We got $1.08, The whole dinner cost $18 so we added $1.08 plus $18, we got $19.08. Then we multiplied 20 by 19.08 and with the answer divided 100 to find the tip. We got $3.82, then we had to add $19.08 plus $3.82 and got $22.90.

Tickets

We chose to buy the tickets in advance so it only cost $10.00
