Answer:
Step-by-step explanation:
a) You want the ratio ...
(Salena's earnings)/(Drew's earnings)
It is convenient to fill in the numbers from the first line of the table:
(Salena's earnings)/(Drew's earnings) = 31/33
b) Salena's earnings in 4 days will be double her earnings in 2 days.
4 days' earnings = 2×$62 = $124
c) Salena's earnings in 30 days will be 10 times her earnings in 3 days.
30 days' earnings = 10×$93 = $930
_____
<em>Alternate solution</em>
You can go to the trouble to write an equation for Salena's earnings (s) in terms of the number of days (d). That would be ...
s = 31d
Then you can fill in d=4 or d=30 to find her earnings for 4 or 30 days. For this problem, enough information is given in the table that shortcuts can be used, simplifying the problem immensely.

Step-by-step explanation:
Using an exponential function, it is found that f(5.5) = 19.8.
<h3>What is an exponential function?</h3>
An exponential function is a function in which the growth rate is a percentage, modeled by:
In which:
f(3.5) = 25 means that:
f(8.5) = 14 means that:
Hence:
Hence, the function is given by:
Then, when x = 5.5:
