Question 1125685
.
A toy manufacturer makes a toy truck, a toy car, and a toy boat. The production spreadsheet is:

<pre>
Toy	Time to Produce	 Cost to Produce	Profit for Each

Truck	10 minutes	 $1.00	                $1.00
Car	12 minutes	 $0.75	                $1.50
Boat	8 minutes	 $0.80	                $0.60


After accounting for breaks, a worker actually works 400 minutes each day. The manufacturer needs each worker 
to generate a potential profit of $35 each day. Write a system of inequalities that expresses these constraints.
</pre>


<U>Solution</U>


<pre>
10T + 12C   + 8B    <= 400            (working time of 400 minutes restriction)

1T  + 1.50C + 0.60B >=  35  dollars   (each worker to generate a potential profit of $35 each day)
</pre>


I think there is a gap (a hole) in the condition missing (omitting) restriction for the cost - otherwise why 
the cost is mentioned in the spreadsheet ?
