While discussing a problem here on this forum, we should ignore the phraseology as long as it doesn't challenge our common senses, really.
One thing is sure that nothing can be drawn out without blending (1) and (2).
The difference in bill is $30 when 2 more units were produced; hence the 2 units paid Bob $15 each. If Bob has produced 36 or less units last week, then his payment could have averaged $13.33 or more per unit, and if Bob has produced more than 36 units last week, then his payment could have averaged less than $13.33 per unit. But his average payment per unit is still more than $13.33, even when he produced 2 more units this week as compared to the last week. Hence, Bob's production is still less than or same as 36 in the present week and he's still being paid the regular $x for each unit he produced in each statement.
So, now, $15 is the regular rate and at this rate, Bob must have produced 480/15 = 32 units the last week.
