Solution

Given:

• A nursery sells fruit trees of different heights
• Nursery has 54 trees that are less than 5 feet in height
• Expected revenue from the sale of its entire stock is estimated at $2,450

To find:

• How much revenue will come from the sale of trees that are at least 5 feet tall.

Approach and Working:

• Total revenue= Revenue from trees that are less than 5-feet tall+ Revenue from trees that are at least 5-feet tall
• 2450= 54*14.95+ Revenue from trees that are at least 5-feet tall
• We can approximate 14.95 as 15 then 2450+54*15+Revenue from trees that are at least 5-feet tall

• Revenue from trees that are at least 5-feet tall = 1640

Hence, the correct answer is option B.

Answer: B
