$42.50

Step-by-step explanation:

First, we can take the 30% sale into account. We can start by converting 30% into a decimal by dividing it by 100: 30/100 = 0.3. Then, we can multiply that by the original price, 75, to get 75 * 0.3 = 22.5 as the amount given off due to the sale. We can subtract this from 75 to get our sale price of 75 - 22.5 = 52.5. Next, we can utilize the other coupon to get an additional $10 off, so we can subtract that from the original sale price to get the final sale price of

52.5 - 10 = 42.5
