Question

A plastic bin contains red, yellow, and green key chains. Out of 350 key chains, 10% percent are yellow. Of the remaining key chains, 3/5 are green. How many red key chains are inside the bin?

Answer 1

Hey You!

350 * 10% = 35

350 - 35 = 315

315 / 5 = 63

63 × 3 = 189

315 - 189 = 126

There are 126 red keys in the bin! =)
