Answer:
[tex]\pounds36[/tex]
Step-by-step explanation:
Cost of one dress = [tex]\pounds40[/tex]
Cost of one pair of shoes = [tex]\pounds32[/tex]
Cost of one dress and a pair of shoes is [tex]40+32=\pounds72[/tex]
They get half off the price because they buy both
[tex]\dfrac{72}{2}=\pounds32[/tex]
The shipping and handling charge is [tex]\pounds4[/tex].
So, the total amount Ruth has to pay is [tex]32+4=\pounds36[/tex].
