Lizzy: It's Yvette's turn to treat herself and her three best friends to a round of ice cream sundaes. Alicia orders the peanut butter sundae for $7.50. Brant orders the Royal banana split sundae for $10.00. Josh orders the death by chocolate sundae for $8.50 and Yvette orders the cherry jubilee sundae for $9.00. She leaves her waiter a 20% tip. How much will her final bill be?.
Me: Hmmm, let me think. I think this is the detailed solution:
Yvette spent 7.50 + 10 + 8.5 + 9 = $35.00 on ice cream sundaes. Her bill comes to $35.00 and she leaves a 20% tip for the waiter so that's 35 * .20 = $7.00. The bill was $35.00 and she added a $7.00 tip for a total of 35 + 7 = $42.00. Final answer: 42.
