First, we have to find 20% of $40.00 To find it, multiply 0.20 x $40.00 and you get $8

Now, take away the 20% away from $40.00
 $40.00 - $8.00 = $32.00

Next, find 5% of $32.00 We have to multiply 0.05 x $32.00 and you get $1.60

We had $32.00 after the 20% discount, so add $32.00 + 1.60 

Lydia paid $33.60 for her shirt.
