Answer:
$42.12
Explanation:
The original price of the shoes was $65.
Everything is 40% off. Therefore, the new price of the shoes now will be the original price minus 40% of 65.
40% of 65 is 0.4(65) or $26. So, $26 was deducted.
This means that the new price will be $65-$26 or $39.
There’s also an 8% sales tax that will be applied. So, Gretta’s total will be the new price of the shoes plus the sales tax being applied to the shoes.
The sales tax is 8% of 0.08. So, when applied to the shoes, it will be: 0.08(39) or $3.12.
Therefore, the total sum Gretta will pay is $39 (the new price) + $3.12 (the sales tax) for a grand total of $42.12
