- This scenario involves adding both amounts, which would be 102.50 + 39.95, not 102.50 + (-39.95).
B. Nevaeh has $102.50 in his bank account. He then deposits $39.95 into his bank account. How much money does he now have in his bank account?
- Similar to option A, this involves adding both amounts, which would be 102.50 + 39.95, not 102.50 + (-39.95).
C. Nevaeh bought new headphones for $102.50. He then spent $39.95 on a new game. How much money did Nevaeh spend all together?
- This scenario involves summing two expenses, which would be 102.50 + 39.95, not 102.50 + (-39.95).
D. Nevaeh earned $102.50 last weekend. He then spent $39.95 on a new game. How much money from his weekend earnings does he have left?
- This scenario involves taking the total earnings and subtracting the expense. The calculation would be: 102.50 - 39.95, which is equivalent to 102.50 + (-39.95).
