Simplify this solution Beyond the Answer
The sum of 49 and 36 can be represented by the number sentence: \( 49 + 36 = 85 \). So, the answer is 85. For the sandwiches, the number sentence is \( 12 \times 4 = 48 \). Therefore, the cost for four sandwiches will be R48. Lastly, to find out how much change you will receive from R100 after paying R43, the number sentence is \( 100 - 43 = 57 \). Thus, your change will be R57.
