Given as :
The amount on off coupon = $0.50
The total money which Logan can spend = $19.75
The quantity of sandwiches which Logan have to buy = 3
Let The highest price of sandwiches Logan can afford =$x + $0.50

∴ x =
I.e x = $6.58
The amount on off coupon which Logan has = $0.50
So,The highest price of sandwiches Logan can afford = x + $0.50
I.e The highest price of sandwiches Logan can afford = $6.58 + $0.50
Or, The highest price of sandwiches Logan can afford = $7.08
