Eric has 4 ninja throwing stars. His friend Chad has twice as many. Then Jeff bought 2 ninja stars from Chad. Jeff now has 6 throwing stars. How many ninja throwing stars do they have altogether? Let's answer step by step:
We know Eric has 4 stars and Chad has twice that amount, so Chad has 4 x 2 = 8 stars. Then Chad sells 2 of them to Jeff, so Chad has 8 – 2 = 6 stars. Altogether, Eric has 4 + Chad has 6 + Jeff has 6 = 16 stars. The answer: 16.
