Johnny
much does it cost John to by 103 lbs of
onions, and why?

Answer 1

$65.92

Explanation:

We start with the cost of one lb of onions: 0.64.

If we add more lbs, the cost goes up at a rate of 0.64. Therefore if we multiply 0.64 by 103, we'll get the cost of 103 lbs of onions.

Since 0.64 * 103 = 65.92, it costs John $65.92 to buy 103 lbs of onions.

Answer 2

$65.92

Explanation:

The cost per onion is $0.64. So, in order to find the cost for 103 onions, multiply 0.64 * 103 = 65.92
