Cassandra is selling pies, cookies, and brownies for a fundraiser. Cassandra sold each pie for $18, each cookie for $2, and each brownie cost $3. Cassandra made $234
for the fundraiser by selling 61 items. The number of cookies she sold was one less than
five times the number of pies sold. Formulate and solve a system of equations to model
the number she sold of each item. (You will receive partial credit for showing your work,
correctly defining the variables, for formulating the equations, and also for the correct
solutions)
