Answer:
The original price was 520
Step-by-step explanation:
To find this, we first need to note that we paid 75% of the price. This is because we took 25% off from the original. Now we take the price we paid and divide it by the percentage of it which we paid. This will give us the original price.
390/75% = Total
390/.75 = Total
520 = Total
