Question

There are 75% more basketball then football at Modell's Sports Store.If there is a total of 220 basketballs and footballs combined in the store, how many are basketball?

Answer 1

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
