Infant Warmers and Baby Harnesses
Sales Plan

Initial Cost Model

Infant warmer are $30 each to make in order to sell. They are sold at $40 each for a $10 profit. Baby harnesses take $20 to make. They are sold for 30 dollars. Baby harnesses also have a profit of $10. The cost model for my products to be made will be 30w+20b=c. W stands for the quantity of infant warmers and b stands for the quantity of harnesses made. C will be the total cost of the products to be made.

Selling model

The selling model will be represented by 40w+30b=s. W will represent the amount of infant warmers made and b will be the baby harnesses. S will represent the net sale made before omitting the initial cost.

Profit model

The profits being made will be represented by the model 10w+10b=p. W will represent the amount of Infant warmers sold and b will represent the amount of baby harnesses made. P will represent the profit of made.

I will only be able to make 50 or less baby warmers and 60 or less baby harnesses before sales day. Another restriction is I will be able to sell less than 100 products on the day of the sale. They inequalities and equations representing my restrictions are: W<50 or W=50, b<60 or b=60, b>0 or b=0, w>0 or w=0, and w+b<100 or w+b=100.








Selling 60 baby harnesses and 40 infant warmers will satisfy all the restrictions while making the maximum profit.
