Justin earned $200 for working as a student assistant. he spend 30% of his earning to buy a birthday gift for his brother, ryan,. how much is the cost of the gift?

The correct answer would be he spent $60 on the gift

So we want to know how much does the gift Justin bought for Ryan costs if he spent 30% out of 200$. So, lets say justin spent x dollars on the gift, then 30% or (30/100) * 200$=x. Now we solve for x: (30*200) / 100=x and x=6000/100=60. So justin spent x=60$ on the gift.
