Question

Claire runs a rooftop nursery in the heart of the city. One day, she cuts 25 tulips, 32 violets, and 40 sunflowers. She sells the flowers to a local florist at t, v, and s dollars, respectively. Claire’s cost to grow the flowers is 10% less than the total selling price. Which expressions represent Claire’s cost to grow the flowers?

1) (25t + 32v + 40s) + 0.10(25t + 32v + 40s)

2) (25t + 32v + 40s) - 0.10(25t + 32v + 40s)

3) 0.90(25t + 32v + 40s)

4) 1.1(25t + 32v + 40s)

Answer 1

(2) and (3)

Explanation:

(2) shows the total cost of the flowers, minus 10% of the total cost, and 100% - 10% = 90%

(3) shows them taking 90% of the total cost, just like (2)
