Aden ordered a combination of sliders and hot dogs for his family at a local restaurant. Sliders cost $2.25 each and hot dogs cost $1.85 each. Aden's bill came out to $25, not including tax. Write an equation in standard form
that models the possible combinations of sliders, s, and hot dogs, h, ordered. Then calculate the number of sliders
he ordered if he ordered 5 hot dogs.
