The answer is $13
Explanation:
You would first have to find 25% of the original amount. To do so, you must multiply the decimal amount of the percentage (0.25) by the number. The product is 20, or $20. So now that you have found the amount that you have spent your money on shorts, now you must find 65% of 20 to find the sandal spending amount. 0.65 * 20 = 13, or $13. Therefore, you spent a total of $13 on the sandals.
