#1.10x>29+.43x#
Solving the inequality yields that he must sell at least 44 cones to make a profit.

Explanation:

Kevin has a cost of running his business equal to the cost of renting equipment plus the ice cream cone ingredient cost.

So the cost equation is
#C = $29 +$0.43x#
where #x# equals the number of ice cream cones produced.

Kevin also has a revenue equation which describes how much money he takes in.
The revenue is given by
#R= $1.10x# where x is the number of ice cream cones sold.

Kevin will make a profit when revenue is greater than cost. Profit occurs when
#R>C#
Or substituting equations above for R and C
#1.10x>29+.43x#
Solving by subtracting .43x from both sides gives
#.67x>29#
Dividing by .67 gives
#x=43.3#
So needs to sell 44 ice cream cones to start making a profit.
