Answer:

$2784.51

Explanation:

You require ...

(total with tax) ≤ 3000

(total with tax) = (total before tax) + 0.0678·(total before tax)

So,

(total before tax) · 1.0678 ≤ 3000

total before tax ≤ 2809.51

With ...

total before tax = laptop cost + case cost

we have ...

laptop cost + case cost ≤ 2809.51

laptop cost ≤ 2809.51 - 25

laptop cost ≤ 2784.51

The maximum you can spend on a laptop is $2784.51.
