00:01 Okay, so it says how many different ways can you make 30 cents with pennies, nickels, dimes, or quarters? so what i've tried to do here is i've tried to come up with every possible way.
00:11 So help me think through it.
00:12 So a quarter is 25 cents.
00:14 I could do one quarter and one penny.
00:17 So that's one way.
00:18 I could do one quarter and one nickel.
00:20 That's a second way.
00:22 Now, there's not another way for me to make 30 cents with a quarter.
00:26 So involving the quarter, i only have two ways.
00:30 Now for a dime, i could do one dime and 20 pennies.
00:34 I could do two dimes and 10 pennies.
00:37 So just dimes and pennies, that's the only way.
00:41 Or i could do one dime, two nickels and 10 pennies.
00:46 10, 20, 30.
00:47 I could do one dime, three nickels, and five pennies.
00:51 I could do two dimes, one nickel, and five pennies.
00:59 I could do one dime, one nickel, and, 15 pennies.
01:04 I could do one dime and four nickels.
01:06 I could do two dimes in 10 pennies.
01:10 Oh, i've already got that.
01:12 That's there.
01:13 So i need to erase this one.
01:14 That was too much.
01:17 I already listed it.
01:20 So no...
