Check if my answers are correct.
1.A girl bought 2 CDs and 3 DVDs for $92. Each DVD costs $4 more than the CDs. What is the price of each CD and DVD?
My answer: CDs $16 and DVDs$20
2.A boy bought 20 stamps, some for 30 cents and the rest for 20 cents. If he spent $5.50 on the stamps, how many did he buy of each one?
My answer: 30c stamps 15, 20c stamps 5

#1 works: 32+60=92
#2 works: 4.50+1.00=5.50
nice work (I guess, since you don't show it, but you did get the right answers!)
