i don't want to know the answer to the question i would just like to know how to solve it. please help! thank you!!

i remember correctly i had this on one of my homeworks . 4032 = 8 therefore 8%
because if you subtract 40  8% 
thank you so much<3

Percent change=(finalinitial)/initial * 100
= (4032)/32 *100
