Answer:
7.2 years
Step-by-step explanation:

where f(t) is the length and t is the number of years old
given the Mike measures 148 cm, we need to find out the age
So we plug in 148 for f(t) and solve for t

divide both sides by 200

Now subtract 1 from both sides

Divide both sides by -0.956

Now take ln on both sides



divide both sides by -0.18
t=7.2
So 7.2 years
We have (2/3)÷5 = 2/15 advertisments for 1 page;
Then, we have 98 · (2/15) = 12.2(6) advertisments for 98 pages;
The nearest whole page is 12.
