The sandwich is sold for $4.76
Explanation-
Divide the total cost of the sandwich by 100 to find what 1% would equal (0.028) then multiple that by the percent the deli sells the sandwich( 170%) which gets you $4.76
Just divide them: 8.76*106/8.76*102= 106/102=1.04
so first number is 1.04 times second number
