A toy manufacturer makes a toy truck, a toy car, and a toy boat. The production spreadsheet is:
Time to Produce Cost to Produce Profit
10 minutes $1.00 $1.00
12 minutes $0.75 $1.50
8 minutes $0.80 $0.60
First row is for trucks, second for cars, and third for boats.
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.

Question

A toy manufacturer makes a toy truck, a toy car, and a toy boat. The production spreadsheet is:
Time to Produce	Cost to Produce	Profit 
10 minutes	                $1.00	        $1.00
12 minutes	                 $0.75        	$1.50
8 minutes	                        $0.80	         $0.60
First row is for trucks, second for cars, and third for boats. 
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.

I think one of the equations should look like this 10t + 12c + 8b ≤ 400. If t = trucks, c = cars, and b = boats.
