Question

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?

The flower chart is prices for half dozen
Roses - $5.29
Carnations-$3.59
Tulips-$4.79

Answer 1

Samantha's estimate is wrong. She would definitely spend way more on the flowers then just $14.00. Here is why i think so:
Roses-For all 6 of them they would be about $11.29
Carnations-They would be about $7.59
Tulips:They would be about $12.79
In all the total would come around to $31.67.
I also want to make it clear that i didn't round these,i added them in my head.

Answer 2

Roses can be founded to $5
Carnations can be rounded to $4
Tulips can be rounded to $5

5 + 4 + 5 = $14
