Question

ms. mills, the head librarian at the franklin county library, can spend at most $4,900 to expand the children’s section of the library. when she buys from a particular discount seller, paperback books cost $3 each and hardback books cost $7 each. write the inequality in standard form that describes this situation. use the given numbers and the following variables. x = the number of paperback books y = the number of hardback books

Explanation:

Step1: Define total cost of paperbacks

Total cost for paperbacks: $3x$

Step2: Define total cost of hardbacks

Total cost for hardbacks: $7y$

Step3: Sum costs, set ≤ budget

Total cost ≤ $4900$, so $3x + 7y \leq 4900$

Answer:

$3x + 7y \leq 4900$
