Q: Five friends eat at Wendy's and ordered the following: a platter of Taco Salad that cost $10, 5 orders of Dave's Single hamburger that cost $5 each, 4 sets of french fries that cost $2.50, and 5 cups of peach lemonade that cost $2 each. How much will each of them pay if they will split the bill equally?
A: The cost of 5 pieces of Dave's Single hamburger is $5 x 5 = $25. The cost of 4 sets of french fries is $2.50 x 4 = $10. The cost of 5 cups of peach lemonade is $2 x 5 = $10. So, their total bill is $10 + $25 + $10 + $10 = $55. Therefore, each of them will contribute $55 / 5 = $11. The answer is 11.

She wants to send a dozen carnations that cost $4 / dz to each of her 5 teachers, so 4 * 5 = $20. She has 14 friends and she knows a dozen carnations is cheaper than buying 12 single carnations. So 14 - 12 = 2 single carnations are needed. A single carnation cost $0.50 so 2 * .50 = $1.00. All total she will spend 20 + 4 + 1 = $25.00 on carnations. The answer is 25.
