Question: The part of the question that appears missing is to; Write an expression for the number of pennies
The given parameters are;
The denominations of currency Greg has in his pocket = Nickels and pennies
The number of pennies he has = 2 × The number of nickels he has - 3
The number of nickels = n
Therefore, by plugging in the variable for the number of nickels, we have;
The expression for number of pennies = 2 × n - 3
