Cookie Monster made snack bags for the streets picnic that contain three types of snacks: packages of crackers, packages of cookies, and candy bars. A snack bag containing 5 of each type of snack costs $22.50. A snack bag containing 7 packages of crackers, 4 packages of cookies, and 11 candy bars costs $38.25. A snack bag containing 2 packages of crackers, 15 packages of cookies, and 5 candy bars cost $25.50. Solve a system of three linear equations in three variables to determine the cost of one cookie.
