Answer:
11.82%
Step-by-step explanation:
We are given that
Cost to store A=4162
Cost to store=$155
Cost to store C=$160
Markup for store A=40%
Markup for store B=30%
Markup for store C=25%
Markup price=Cost price\times (100+markup)
Markup price for store A=[tex]162\times (100+0.4)=[/tex]$226.80
Markup price for store B=[tex]155\times 1.3[/tex]=$201.50
Markup price for store C=[tex]160\times 1.25=[/tex]$200
So, the best deal is store C.
If we purchased from store A then the price should be less than store C.
It means the price of store A should be less than $200 that is $199.99.
Discount=226.80-199.99=$26.81
Discount %=[tex]\frac{26.81}{226.80}\times 100=11.82[/tex]
Hence, the store A must offer discount 11.82% to buy the system there.
