Solution

## The correct option is D 2 dollarsTerry spends 115 of his allowance on the gaming set. Now, we know that 115 is a mixed fraction. We can write this mixed fraction as an improper fraction using the formula: (Whole×Denominator)+NumeratorDenominator Here, Whole = 1 Denominator = 5 Numerator = 1 Thus, 115=(1×5)+15=5+15=65 Now, Terry's monthly allowance = 10 dollars ∴ Amount spent on the gaming set = 115 part of 10 dollars=65 part of 10 dollars So, the amount will be: 65 of 10=65×10 = 12 dollars Hence, additional amount Terry spends on the gaming set = 12 − 10 = 2 dollars
