A computer store is placing an order for computers and tablets. Each computer costs $875, and each tablet costs $235. The store can spend at most $10,000 for these computers and tablets. The computer store has a limited amount of space for displaying the new computers and tablets. Each computer takes up 4 square feet of space, and each tablet takes up 3 square feet of space. The store has only 45 square feet of display space available for the new computers and tablets. The system of inequalities shown can be used to determine possible combinations of computers, x, and tablets, y, the store can order.
875x + 235y ≤ 10,000
4x +3y ≤ 45
Which combinations of computers, x, and tablets, y, can the computer store order?
(7,9)
(7,9)
(10,2)
(10,2)
(8,4)
(8,4)
(5,9)
(5,9) is not a valid combination because it violates the second inequality.
The valid combinations are:
- (7,9)
- (10,2)
- (8,4)
