How much did he give? ** He gave 2*20=$<<2*20=40>>40.
How much did the bread cost? ** So the total cost was 40-16=$<<40-16=24>>24.
How much does each slice cost? ** That means each slice costs 24/3=$<<24/3=8>>8.
How much does each slice cost, in cents? ** That means it costs 8*100=<<8*100=800>>800 cents.
How much does each slice cost, in cents? ** So each slice is 800/20=<<800/20=40>>40 cents.
