Answer:
Recall that the equation we created was:
y = 2x + 10
where y represents the number of leaves and x represents the number of weeks since spring has started.
To find the expected average number of leaves on a tree 8 weeks after spring has started, we need to evaluate the equation for x = 8:
y = 2(8) + 10
y = 16 + 10
y = 26
Therefore, the expected average number of leaves on a tree 8 weeks after spring has started is 26.
