Ice cream is best stores at 4 degree f with an allowance of 3 degree f. what is the best range to store ice cream?
a) 4 to 8
b) 7 to 10
c) 1 to 7

1°F to 7°F  is the best range to store ice cream.

Step-by-step explanation:

The ideal storage temperature of ice cream = 4°F

The allowance in the temperature is 3°F

So, the range of the store = 4°F ±  3°F

Now, 4°F + 3°F  =  7°F

and    4°F -  3°F  =  1°F

Hence, 1°F to 7°F  is the best range to store ice cream.
