Answer :
The mathematical sentence that best describes the relationship is: 5c + 150 = 423.
In this scenario, we are given that Andy bought 5 white chocolates and paid a total bill of 423Php, including the cost of the gummy bears. We want to represent the relationship between the price of each white chocolate, denoted as c, and the total bill.
Since Andy bought 5 white chocolates, the cost of those chocolates would be 5 times the price of each chocolate, which is 5c. Adding this to the cost of the gummy bears, which is 150Php, the sum should equal the total bill of 423Php.
Therefore, the appropriate mathematical sentence is 5c + 150 = 423.
