Final answer:
The average price of the pickup truck increased by approximately 64% from 1993 to 2015, calculated using the percentage change formula.
Step-by-step explanation:
To calculate the percentage increase in the average price of the pickup truck from 1993 to 2015, you can use the formula for percentage change, which is:
(New Price - Original Price) / Original Price × 100
If the average price of the pickup truck in 1993 was $17,500, and in 2015 it was $28,700, then:
($28,700 - $17,500) / $17,500 × 100 = $11,200 / $17,500 × 100 ≈ 64%
Therefore, there was approximately a 64% increase in the average price of the pickup truck over that period.
