Explanation:

Question 4 (Marilyn's Package Weight)

Step1: Convert mixed numbers to decimals

Gift 1: \( 4\frac{1}{2} = 4.5 \) pounds
Gift 2: \( 3\frac{2}{5} = 3.4 \) pounds

Step2: Sum the weights of the gifts

\( 4.5 + 3.4 + 8.4 = 16.3 \) pounds (gifts only)

Step3: Add the shipping box weight

\( 16.3 + 1.3 = 17.6 \)? Wait, no—wait, recalculate:
Wait, \( 4.5 + 3.4 = 7.9 \); \( 7.9 + 8.4 = 16.3 \); \( 16.3 + 1.3 = 17.6 \)? But option D is 17.60. Wait, did I miscalculate? Wait, no—wait, Gift 2: \( 3\frac{2}{5} = 3.4 \), Gift 1: 4.5, Gift 3: 8.4. Sum: 4.5 + 3.4 = 7.9; 7.9 + 8.4 = 16.3. Then add box 1.3: 16.3 + 1.3 = 17.6. So D is 17.60.

Step1: Calculate cost of two $15.50 gifts

\( 2 \times 15.50 = 31.00 \) dollars

Step2: Calculate cost of three $8.25 gifts

\( 3 \times 8.25 = 24.75 \) dollars

Step3: Sum the two amounts

\( 31.00 + 24.75 = 55.75 \) dollars

Step1: Calculate tax amount

Tax = \( 0.08 \times 55.75 = 4.46 \) dollars

Step2: Add tax to subtotal

\( 55.75 + 4.46 = 60.21 \) dollars

Answer:

D. 17.60 pounds
