Answer:
5a. $9.20
5b. 75 clicks
Explanation:
You are asked to make use of the given relationship between number of clicks (c) and budget remaining (A).
__
5a
The number of clicks is given as c = 52, so the budget remaining is ...
A = 30 -0.40(52) . . . . . use c=52
A = 30 -20.8 = 9.20
There will be $9.20 left at the end of the day.
__
5b
The number of clicks needed to use up the budge can be found by solving for c when A=0.
0 = 30 -0.40c . . . . . use A=0
0.40c = 30 . . . . . . . add 0.40c
c = 30/0.40 = 75 . . . . . divide by 0.40
The ad was clicked 75 times if there is no daily budget remaining.
