an initial velocity of 98 m/s. The function that models heigh
with respect to time (in seconds) is h(t) = 5 + 98t – 4.9t2
Part A: Complete the table below.

  Lana is saving at the greater rate.

Step-by-step explanation:

Given : Lana puts $50 each week into her savings account.

From the graph of Eliana 's Account , the line is passing through (0,0) and (2,94).

Rate of change of a line =

It means Eliana saves $ 47 each week [Since , y axis represents Total Savings and x axis represents Time ( weeks).]

Clearly , $50 per week  > $47 per week

It means Lana is saving at the greater rate.
