Final answer:
To find the Trey discount on a computer that Liz bought for $500 with a discount rate of 15%, we multiply the original price by the discount rate.
Step-by-step explanation:
To find the discount on a computer, we need to multiply the original price by the discount rate. In this case, the original price is $500 and the discount rate is 15%. We can calculate the discount as follows:
Discount = Original Price * Discount Rate
Discount = $500 * 0.15
Discount = $75
Therefore, the Trey discount on the computer that Liz bought for $500 is $75.
