Question
The cost of making cookies 𝑝% is given by formula
𝐶(x) = 4𝑝/100 − 𝑝
where 𝐶 is measured in hundreds of thousands of dollars. If less than $600,000 is spent,
what is the percentage of the cost of making cookies?

I'm guessing you meant
4p/(100-p)
since 4p/100 - p is always negative
So
4p/(100 - p) < 600
4p < 60000 - 600p
604p < 60000
p < 60000/604 = 99.33%
4p/(100-p)
since 4p/100 - p is always negative
So
4p/(100 - p) < 600
4p < 60000 - 600p
604p < 60000
p < 60000/604 = 99.33%
