Answer:
192 basketballs and 28 footballs
Step-by-step explanation:
lets take "b" as the number of basketballs and "f" as # of footballs
so b+f=220
first we need to find what 75% of 220 is:
0.75*220=165
there are 165 more basketballs
hence b-165=f
since we got what f is equal to we can substitute it into first equation:
b+(b-165)=220
b+b-165=220
2b-165=220
2b=385
b=192
hence 192+f=220
f=28
