Answer: The sunflower be 50 inches tall after 6 weeks.
Total height of sunflower in w weeks = 20+1.5 w,
Step-by-step explanation:
Given: In the beginning, the sunflower was 20 inches tall.
The sunflower then began to grow at a rate of 1.5 inches per week.
Then, total height of sunflower in 6 weeks = 20+1.5 ×20, where 1.5 ×20= growth in 6 weeks
= 20+30
= 50 inches
So, the sunflower be 50 inches tall after 6 weeks.
Let w = number of weeks, then
Total height of sunflower in w weeks = 20+1.5 w, where 1.5 w= growth in w weeks.
