A computer store is placing an order for computers and tablets each computer costs 875$ and each tablet costs 235$

To calculate the total cost of the computers, you need to know the quantity of computers being ordered. Let's assume the store is ordering "x" computers.

The cost of each computer is $875. Thus, the total cost of all the computers would be 875*x dollars.

To calculate the total cost of the tablets, you also need to know the quantity of tablets being ordered. Let's assume the store is ordering "y" tablets.

The cost of each tablet is $235. Therefore, the total cost of all the tablets would be 235*y dollars.

The total cost of the order, including both computers and tablets, is the sum of the cost of computers and the cost of tablets:

Total cost = 875*x + 235*y dollars.
