Question 6 • WI-Mathematics Grade 8 A
The tree’s height increases by 1 foot every 0.5 year, which is 2 feet per year. From 4 years after transplanting to the transplant date is 4 years, so subtract 4 × 2 = 8 feet from its height of 12 feet: 12 − 8 = 4 feet. The tree was 4 feet tall when transplanted, which is choice C.
