A:
we know that

for 15000 species of butterflies
if there are 67 butterfly species for every -------------> 22,000 insect species
for 15000 species of butterflies-------------------------------> X
X=15000*22000/67---------> X=4925373.13 insect species

for 22000 species of butterflies
if there are 67 butterfly species for every -------------> 22,000 insect species
for 22000 species of butterflies-------------------------------> X
X=22000*22000/67---------> X=7223880.60 insect species

the answer is
