so Meg's friend is a faster reader, if Meg takes 3/5 of an hour I guess, to read one book, her friend takes 2/3 of that.

how much is 2/3 of 3/5?  well, is just their product.


\bf \cfrac{3}{5}\cdot \cfrac{2}{3}\implies \cfrac{3}{3}\cdot \cfrac{2}{5}\implies 1\cdot \cfrac{2}{5}\implies \cfrac{2}{5}\impliedby \textit{for one book only} \\\\\\ \stackrel{first~book}{\cfrac{2}{5}}+\stackrel{second~book}{\cfrac{2}{5}}+\stackrel{third~book}{\cfrac{2}{5}}\implies \cfrac{6}{5}\implies 1\frac{1}{5}\impliedby \textit{for three books}

Answer:

2998 ; 17%

Step-by-step explanation:

Given the function:

t(c)=-3970.9(ln c)

c = % of carbon remaining ; t = time

1.) c = 47% = 47/100 = 0.47

t(0.47) = - 3970.9(In 0.47)

t = - 3970.9 * −0.755022

t = 2998.119

t = 2998

B.)

t = 7000

t(c)=-3970.9(ln c)

7000 = - 3970.9(In c)

7000 / - 3970.9 = In c

−1.762824 = In c

c = exp(−1.762824)

c = 0.1715596

c = 0.1715596 * 100%

c = 17.156% ; c = 17%
