Question

Samantha is making some floral arrangements. The table show the prices 1/2 dozen of each type of flower.

Rose$5.29 Carnation$3.59Tulip$4.79 Samantha wants to buy 6 roses, 4 carnations and 8 tulips. She estimate that she will spend 14$ on these flowers. Do you agree?

Answer 1

Working:
$5.29 + ((2/3) x 3.59) + ((4/3) x 4.79)
= $14.07 (to 2d.p.)

So, she estimated correctly that she will spend around $14 on the flowers but slightly more than $14, so I don't really know if you should say that she estimated correctly or not
