Josette found 16 coins in her purse. She had 2 more nickels than pennies and 7 fewer quarters than pennies. Josette modeled the
scenario in a table and then wrote the equation p + (p + 2) + (7 – p) = 16.
Is Josette’s equation correct? If not, what was her mistake.
A): Her equation is correct.
B): The variable should have been the number of nickels.
C): Instead of finding the sum, she needed to write an equation to find the difference.
D): The number of quarters was translated incorrectly and should be p – 7.
