represent the days as a variable
days= x
remeber that 80c is the same as $0.80
write an equation that models this situation
[tex]0.80x>25.50[/tex]solve the equation for x
[tex]\begin{gathered} \text{0}.80x=25.50 \\ x>\frac{25.50}{0.80} \\ x>31.875 \end{gathered}[/tex]according to this, after 31.875 days he will have enoght for the hat
