Step-by-step explanation
Grace will buy one gallon of milk, that costs $3.59 and some apples - she doesn't know how many apples, so let's call the amount of apples 'x'. Each apple costs $0.60. Since Grace has $6 to buy all these things, the value of the gallon of milk plus the value of the apples must be at most $6.
In numbers, this means that $3.59 + $0.60 x must be equal or less than $6.
Answer
The inequality is:
