A package of 8 paper rolls costs 6.00 dollars. Enter the cost per roll in dollars.
Правильный ответ
0.75
Объяснение
Dividing the 6.00-dollar price by 8 rolls gives 0.75 dollars for each roll. Dividing 8 by 6 would give rolls per dollar, which is useful in another comparison direction but is not the requested price per roll.
