At least 5 feet trees means it is the sum of the trees having height of 5 ft to 6 ft & more that 6 ft
Total revenue is 2450 Dollar
Less than 5 feet tall trees revenue = 54*15 = 810
At least 5 feet Trees Revenue = Total - 810 = 2450 - 810 = 1640 dollar

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

The ballparking answers above are right on! The answer explanation in the OG has us multiplying by 14.95 and working with nonsense like 807.30 to end up with an answer of 1642.70. The OG is awesome for sourcing questions, but they only suggest ballparking as the best way to go about things on about 1% of PS questions. By my calculation, ballparking is useful on roughly 12% of PS questions!!! Get good at spotting opportunities to ballpark, and you can get problems correct faster and with less brain damage and fatigue!
