Cynthia makes iPhone covers to sell using small seashells and beach pebbles. She can create at most 40 covers with seashells and 50 with pebbles on any given day She creates at least 80 or more covers, in total, each day. It costs her $1.25 in material to create a cover with seashells while a pebble cover costs $1.75. What is the minimum cost to produce the targeted number of covers, on a daily basis?
