Solution,

Arranging the data in ascending order:

0,1,1,2,2,3,3,4,4,4,4,4,4,4,5,6,6,7,8,9

N(total number of items)= 20

Now,

Median:

(\frac{n + 1}{2)} ) ^{th \: item}  \\  =  (\frac{20 + 1}{2} ) ^{th \: item}  \\  =  \frac{21}{2}  \\  = 10.5 \: th \: \: item

Again,

Median:

\frac{10  \: th \: item + 11 \: th \: item}{2}  \\  =  \frac{4 + 4}{2}  \\  =  \frac{8}{2}  \\  = 4

Simply find the total medium cofees sold
then divide that by the number of medium cofees that weren't caffeinated

so..
66 \div 44 = x
then
100 \div x = percentage

so x will be 1.5 & 100 ÷ 1.5 = 66.666...
rounded is 67%

MissTica
F(x) = 5x − 1

and g(x) = 3x − 9


g(x) - f(x) = (3x − 9) - (5x − 1) ===> -2x-8
