Alonzo makes (X) dollars for every (Y) hour he works. His total paycheck is (Z). Multiply the how much he makes per hour (X) by how many hours he worked (Y) to find out his total paycheck (Z).
XY = Z
From the facts, we know both Y and Z.
Y = 17 hours
Z = $221
From there, we can plug those two factors into the equation to solve for X.
X(17) = $221
X = 13
Therefore, Alonzo is making $13 per hour of work.
To find out how many hours he works to make $104, plug is $13 for X and $104 for Z to solve for Y.
(13)(Y) = $104
Y = 8
Therefore, Alonzo works 8 hours to make $104.
