Answer:
Expression for the total cost is $1J.
Explanation:
Given that each granola bar costs $1.
Now we need to write an expression that shows the total costs of the granola bars using the variable J.
So let's assume that the number of granola bars = J
then total cost of g granola bars = (J)($1) = $1J
Hence required expression for the total cost is 1J dollars.
