the original price p of a pair of shoes if the sale price is $13 after a 75% discount:
p-%2875%2F100%29p=13
p-75p%2F100=13
%28100p-75p%29%2F100=13
25p=13%2A100
p=%2813%2Across%28100%294%29%2Fcross%2825%291
p=13%2A4
p=52
so, the original price of a pair of shoes is $52

check:
the original price: $52
discount:$%2875%2F100%2952=0.75%2A52=39
sale price: $52-39=13
