Answer:
$7.04
Explanation:
To find the total cost of the milk Ken bought, you can multiply the number of gallons by the cost per gallon.
Ken bought 3 and 1/5 gallons of milk, which is equivalent to 3.2 gallons (since 1/5 is the same as 0.2 when expressed as a decimal).
Now, multiply the number of gallons by the cost per gallon:
Total Cost = 3.2 gallons × $2.20/gallon
Total Cost = $7.04
So, the total cost of the 3 and 1/5 gallons of milk is $7.04.
