Numbers English Contest #17

West Electronics is a specialty instrumentation manufacturer for water treatment plants. They have developed a loyal following in North America for a line of their sensors that sells for $1490. 

Fixed expenses are $234,200 per month. Variable expenses are $137 per unit.

If fixed costs rise by $12,500 and variable costs jump to $151, what is the change in the per unit margin (based on monthly sales of 200 units) expressed in percentage points? The selling price stays the same.

Please note that this short passage of English text requires at least six sets of calculations to get the right answer. Can you translate this English to frame the calculations properly?
