If Bob produces 36 or fewer in a week, he is paid X dollars per item. If Bob produces more than 36 items, he is paid X dollars per item for the first 36 items, and 3/2 times that amount for each additional item. How many items did Bob produce last week?

1). Last week Bob was paid total of $480 for the items that he produced that week. 2). This week produced 2 items more than last week and was paid a total of$510 for the item that he produced this week.

St -1 == not sufficient. Doesnt say anything about the items or individual item price.

St-2 == not sufficient. Doesnt say anything about the individual item price to construct the equation.

From sts (1) and (2),
510-480 = 30 for 2 items
so for each item \$15. Now we don't know if these 2 items are part of 36 items or more than that.
It could be that these 2 items are part of 36 items, so x= 15 and then x1(excess over 36 items) = 22.5
or it could be that these 2 items are over 36 items so x1=15 and x = 10
