Answer:
$(27.75 - 3g)
Explanation:
If Grant too $27.75 to the movies last friday
Cost of each movie tickets = $g
Grant bought 3 tickets, so his total cost = $(g+g+g)=$(3g)
The money Grant had leftover = Total Amount Taken to the movie - Total movie cost
=$(27.75 - 3g)
Therefore Grant leftover money after he bought 3 tickets is represented by $(27.75 - 3g) where g is the cost of one movie ticket.
