Step-by-step explanation:

the growing rate is given by the ecuation

$p(t)=0.8(t)^{3} +3.5$ thousand per hour

for t=2 we have

$p(2)=0.8(2)^{3} +3.5 = 9.9$ thousand

$p=9900\\$ bacterias

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%

$67\%$
