is the constrain correct?

shouldnt be like: a+b+c+d+e =500, a+b+c+d+e =600 , a+b+c+d+e =2100 ?

because in the question the minimum requirement is given which is 500 , 600 and 2100.

and he wants the cheapest combination that meet the minimum requirements.

if he says must contain a minimum requirements that will be like the solution in the pic.

am i right ? correct me pls
