  Total cost to purchase the oil to heat the house for one day when the average temperature is 10^oF,

DAY:

From oil heating chart, we know that amount of oil required to heat a house of the average outside temperature is 50^oF

  Total cost to purchase the oil to heat the house for one day when the average temperature​​​​​​​ is 50^oF,
