Answer:
she spent total price of 13 on the picnic table
Explanation:
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
= 65 % ×40
=
![(65)/(100) * 40](https://img.qammunity.org/2020/formulas/mathematics/middle-school/1svjp0deg0eozx6aiwpf3ishsw69wfkyf6.png)
=26
Hence after the discount amount
Original price – discount price
= 40-26 = 13
Hence she spent total price of 13 on the picnic table
