Hi Malorey,

If she makes X floor lamps and Y table lamps per week, then

75 min = 1hr + 15 min = 5/4 hr , 50 min = 5/6 hr

The number of hours per week 5X/4 + 5Y/6 = (1/12)(15X + 10Y)

$25 material cost per floor lamp, $20 material cost per table lamp

The cost of materials is 25X + 20Y

The constraints for the craftswoman are;

X ≥0, Y ≥0

(1/12)(15X + 10Y) ≤ 40 or 15X + 10Y ≤ 480 and 25X + 20Y ≤ 900
