The correct option is b which is 0.70p.
Given to us,
original price of shoes = p,
Discount on shoes = 30%
As we know after giving the discount the value of the shoes will be 70% of the original price, therefore,
[tex]\bold{p=100\%\ price\ of\ shoes = \dfrac{100}{100}\times p = p}[/tex]
After 30% discount,
[tex]\bold{p=(100\%-70\%) price\ of\ shoes}[/tex]
[tex]\bold{p=70\%\ price\ of\ shoes = \dfrac{70}{100}\timesp= 0.7p }[/tex]
Hence, the correct option is b which is 0.70p.
