If 4 gallons of milk costs $16.76, how much would 7 gallons of milk cost?
2 answers:
Answer: $29.33
Step-by-step explanation: T solve this problem, we first need to find the unit price for 1 gallon of milk. Unit price means the cost per unit which in this case is the cost per gallon of milk.
Since we know that it costs $16.76 for 4 gallons of milk, to find the cost for 1 gallon, we need to divide 4 into $16.76 or 4 into 16.76.
Using our long division, we find that 1 gallon costs $4.19.
Now, that's not our final answer. Remember we want ti find the cost of 7 gallons so we simply multiply 4.19 by 7 to get 29.33.
So 7 gallons of milk will cost $29.33.
