Q. Suppose that you have $40\$40 to spend on records that cost seven dollars each write an expression for the number of dollars left after you by XX
  1. Identify Cost and Amount: Identify the cost per record and the initial amount of money.\newlineCost per record: $7\$7\newlineInitial amount: $40\$40
  2. Calculate Total Cost: Calculate the total cost for XX records.\newlineTotal cost for XX records = 7×X7 \times X
  3. Write Remaining Money Expression: Write the expression for the remaining money after buying XX records.\newlineRemaining money = Initial amount - Total cost for XX records\newlineRemaining money = 40−7X40 - 7X
