Let's solve this equation for q

 $$0=80q-0.05q$$ Combine like terms on the right hand side of the equation $$0=79.95q$$ Divide by $$79.95$$ on both sides of the equation $$0=q$$ We're done!

He/she doesn't mean that, TheXSquaredFactor.

$$0 = 80q-0.05q^2\\ 0.05q^2-80q = 0\\ q^2 - 1600q=0\\ q(q-1600)=0\\ \text{Set each factor to 0}\\ q= 0\text{ or }q = 1600$$
