b.
0.384; 0.3306
d.
87; 95

Answer 1

a. 34.8; 33.06

Explanation:

The computation is shown below;

since in the question it is mentioned that that if the price is $40 so if offered the 13% discount

So the 13% discount on $40 is

= $40 - 13% of $40

= $34.80

Now additional 5% is also provided

So,

= $34.80 - 5% of $34.80

= $33.06

Therefore the first option is correct
