Monica earned twice as much as Samuel mowing lawns. If Monica earned $48, how much did Samuel earn?

Samuel earned $24.

To find out how much Samuel earned, we can set up a proportion using Monica's earnings.

Let S represent Samuel's earnings. We know that Monica earned twice as much as Samuel, so we can set up the equation:

Monica's earnings / Samuel's earnings = 2

$48 (Monica's earnings) / S (Samuel's earnings) = 2

Now, we can solve for Samuel's earnings by cross multiplying:

48 = 2S

Dividing both sides by 2 gives us:

S = 48 / 2

Simplifying, we find that Samuel earned $24.
