Answer:
t = -24*log(2/3)
Step-by-step explanation:
The expression is:
V = 22,500*10^(-t/12)
Replacing with V = 10,000 and isolating t, we get:
10,000 = 22,500*10^(-t/12)
10,000/22,500 = 10^(-t/12)
4/9 = 10^(-t/12)
(2/3)² = 10^(-t/12)
2*log(2/3) = -t/12
-12*2*log(2/3) = t
t = -24*log(2/3)
The ad cost for half page Saturday after discount is
15% of 380 = 0.15×380 = 57
380 - 57 = 323
The ad cost for half page Tuesday after discount is
15% of 330 = 0.15×330 = 49.5
330 - 49.5 = 280.5
Cost of the ads for 10 Saturdays and 10 Tuesdays
(10×323)+(10×280.5) = 3230+2805 = 6035
