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

Step-by-step explanation:

10% of yellow out of 350 we get 35 key chains

3/5 are green out of 350 we get 210 key chains

210+35=245

300-245=55

therefore 55 red keychains are there inside the bin.
