If Joe has 7 songs how long can each song play for if the maximum amount of minutes his DVD can play for is 5 minutes?

1 answer:

7 0

The question is asking for the maximum amount of time each song could be but still five minutes.
5 minutes=300 seconds

300/7=42.85
So each song can play for approximately 42.85 seconds.

Helen bought a coat at a 20% off sale and saved $12. what was the original price of the coat?

miskamm [114]

If you decrease a price by 20% you multiply the original cost by 0.8
So, if y times 0.8 = $12, then you do y=12/0.8 which is 15.
The original cost is $15.
