Last year's computer model is on sale for $799. You can add more memory to the computer. Each chip of 8 megabytes of memory costs $25. How many megabytes of memory can you add if you have at most $1,000 to spend.

1,000 - 800 = 200

200/25 = ?

To find out how many megabytes of memory you can add, we first need to determine the remaining budget after purchasing the computer model.

Subtract the cost of the computer $799 from your total budget $1,000:
$1,000 - $799 = $201

Now, divide the remaining budget by the cost of each memory chip to find out how many chips you can afford:
$201 ÷ $25 = 8.04

Since you cannot have a fraction of a memory chip, you would need to round down to the nearest whole number. Therefore, you can afford to purchase 8 memory chips.

To determine the total memory capacity you can add, multiply the number of chips by the memory capacity of each chip:
8 chips * 8 megabytes/chip = 64 megabytes

So, you can add up to 64 megabytes of memory to the computer if you have at most $1,000 to spend.
