Answer:

$190

Step-by-step explanation:

With a 20% discount, John pays 80% of the computer price. (since 100% -20%= 80%)

Let $C be the original price of the computer.

80%C= 760

[tex] \frac{80}{100} C = 760 \\ C = 760 \div \frac{80}{100} \\ C = 760 \times \frac{100}{80} \\ C = 950[/tex]

Discount

= 20% C

[tex] = \frac{20}{100} (950) \\ = 190[/tex]

Thus, the discount was $190.
