Larry is making custom signs to sell at his shop. the cost of making each sign is $50 plus $4.50 per sign, he will sell them for $15 each. find the number of signs he must sell to make a profit

The best way to answer this would be making a graph

For 1 sign it costs 54.50 and he makes 15

For 2 signs it costs 59 and he makes 30

For 3 signs it costs 63.50 and he makes 45

For 4 signs it costs 68 and he makes 60

For 5 signs it costs 72.50 and he makes 75

This means that after 5 signs Larry will be making profit

faster, im not sure why but i know it is faster

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
