b.![b=\frac{300-a-s}{2}](/tpl/images/0567/4051/dc867.png)
Step-by-step explanation:
a. let s denote shirts and a denote athletic shoes. given that the shirts are priced the same and that the total amount spent was $95.
#The price of each shirt can be calculated using the expression;
Hence, the price of each shirt is obtained using![s=\frac{95-a}{2}](/tpl/images/0567/4051/ecbd3.png)
b. First we have to understand that slacks and shoes have to be bought in pairs as a single unit but a pair of blazer is 2 units.
Let a denote the slacks, s shoes and b the blazer.
#Therefore our expression will be:
Hence, the price of each blazer is calculated using the expression![b=\frac{300-a-s}{2}](/tpl/images/0567/4051/dc867.png)
