The answer is C.(There are 8 bacteria cells after 15 minutes.)
Millionare means having $1 million or more.
He will be a millionare in 2 years... I think
F(C) = 9/5C + 32
I'll just change F(C) to y and 9/5C to 9/5x.
y = 9/5x + 32
inverse...
x = 9/5y + 32
9/5y = x - 32
y = 5/9x - 160/9
Sooooo
F(C) = 5/9C - 160/9
2.666 is equal to 2 2/3
or as an improper fraction: 8/3
