You can get 5GB additional memory and the total memory will be 9GB.
Step-by-step explanation:
Given,
Cost of laptop with 4GB memory = $495
Amount you have = $980
Cost per GB = $97
Let,
x be the additional memory in GBs you can buy.
As you cannot spend more $980, therefore,
Cost of laptop + Additional memory*Price per GB ≤ Amount you can spend
[tex]495 + 97x\leq 980\\97x\leq 980-495\\97x\leq 485[/tex]
Dividing both sides 97
[tex]\frac{97x}{97}\leq \frac{485}{97}\\x\leq 5[/tex]
Therefore, you can buy 5GB more memory.
Total memory = Memory laptop already have + additional memory
Total memory = 4GB + 5GB
Total memory = 9GB
You can get 5GB additional memory and the total memory will be 9GB.
