anonymous · Answer

OH.. ok.. just a minute

anonymous · Answer

x = the total number of bike riders.

76% of them do not wear helmets
24% of them do wear helmets

The word "of" means to multiply.

If we add the number of riders who DO NOT wear helmets and the number of rider who DO wear helmets we get all of the riders.

However, we already KNOW HOW MANY DO NOT wear helmets...38.7

The number who DO wear helmets is 24% of the riders = .24x   so

y = .24x + 38.7

WAIT just a minute... I am off.

anonymous · Answer

.76x of the riders do NOT wear helmets

we know that .76x = 38.7   so divide by .76

1st answer    .76x = 38.7

2nd answer     x = 50.92 million people...
