Each piece of lumber is 4 1/6 feet long.

How do we know that? well if you take the numbers you have and divide you can find the answer, so.

Kareem cannot decide which of two washing machines to buy. The seling price of

Phantasy [73]

The first washing machine is 50% off- so it'd be $260 for the final price

The second washing machine was marked down by 20%, so it'd be 416. But then it was marked down another 30% so the final price would be $291

Since the first washing machine was just 50% of $520, it's a better deal rather than 20% of $520, then 30% of $416

I hope my answer was clear enough!
