The inequality that represents the possible combinations of candy bars and lollipops that he can buy is given by:
[tex]0.45x + 0.25y \leq 28[/tex]
The total price can be no more than $28, hence:
[tex]T \leq 28[/tex]
Each candy bar costs $0.45 and each lollipop costs $0.25. x is the number of candy bars and y of lollipops. Hence, the total price is given by:
T = 0.45x + 0.25y.
Hence, the inequality that models the situation is:
[tex]0.45x + 0.25y \leq 28[/tex]
