<u>Answer:</u>
she spent total price of 13 on the picnic table
<u>Explanation: </u>
Original price of the table = 40
Since she paid 10% of the sale tax after the sale then the total amount she spend is
Discount = (discount percentage – sale tax ) × original price
= (75% -10%) × 40

Hence after the discount amount
Original price – discount price
= 40-26 = 13
Hence she spent total price of 13 on the picnic table
