Question

Samantha is making some floral arrangements. The table shows the prices for one-half dozen of each type of flower.

Price for 1/2 dozen flowers rose : $5.29 Carnation : $3.59 Tulip $ 4.79 part A: Samantha wants to buy 6 roses, 4 carnations, and 8 tulips. She estimates that she will spend about $14 on these flowers. Do you agree? Explain your answer.
Part B: Along with the flowers, Samantha bought 4 packages of glass beads and 2 vases. The vases cost $3.59 each and the total sales tax was $1.34. The total amount she paid was $28.50, including sales tax. Explain an strategy she could use to find the cost of 1 package of glass beads.

Answer 1

Sum = 2*3.59 + 1.34 + 14.07 = 22.59

Difference = total - 22.59 = 28.50 - 22.59 = 5.91

Explanation:

Answer 2

1)
6 roses => $ 5.29
4 carnations => $ 3.59/6 * 4 = 2.39
8 tulios => $ 4.79/6 * 8 = 6.39

Sum = 5.29 + 2.39 + 6.39 = 14.07

Then I agree with her.

2) Sum the cost of the vases (2*3.59) + tax (1.34) + flowers (14.07) and subtract from the total (28.50)

Sum = 2*3.59 + 1.34 + 14.07 = 22.59

Difference = total - 22.59 = 28.50 - 22.59 = 5.91

That amount is the cost of the 4 packages of glass beads, then divide by 4 to find the cost of 1 package of glass bead: 5.91/4 ≈ $1.48
