While discussing a problem here on this forum, we should ignore the phraseology as long as it doesn't challenge our common senses, really.duongthang wrote:if Bob produce 36 unit, he is paid x dolar per unit. if Bob produces more than 36 units, he is paid x dolar per unit for first 36 unit and 1.5x per unit for each additional unit. how many unit Bob pruduces last weak

Unit price = 10sanju09 wrote:[
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.

I must confess that I have missed a potential case in the question so without doubt. I should have read other's posts including yours, before playing that suicidal shot. Miss happenings often happen on earth. Nevertheless, I must thank you for this, ajith!ajith wrote:Unit price = 10sanju09 wrote:[

no of units produced last week = 44
Amount paid last week, 480
Amount paid this week , 510
Unit price =15
no of units produced last week = 32
no of units produced this week = 34
Both of these solutions satisfy all the conditions of the question, so how can you be sure of the number of units?
Explanation please, Sanju
