#$45#

Explanation:

The first thing to know is that the function #P(s)=0.50s-30# is the function to find the total profit earned given an amount #(s)# of suckers.

If we want to find the amount of profit earned by selling #150# suckers, we must substitute #150# for #s# in our function and evaluate. So...

#P(150)=0.50(150)-30#

#=75-30#

#=45# Dollars
