Arestaurant uses 80% of its oil in one week. they now have 36 quarts of olive oil left. how do you use a double number line to find the number of quarts the restaurant had at the beginning of the week

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
