Answer:
438.86
Step-by-step explanation:
1. 457 x 0.99 = 452.43 - Decreased by 1%
2. We need to decrease 452.43 again but this time by 3% - 452.43 x 0.97
3. This gives us an answer of 438.8571
4. Finally we need to round this to 2DP, the 7 (438.8571) rounds up so the number to the left increases. This leaves an answer of 438.86
Hope this helps :D
