Answer 2

Answer:

estimated =4200+3600=7800

sum= 4230+3590=7820

Step-by-step explanation:

here 4 digit numbers are given, you have to round each of those two to the nearest 100 i.e. 4200 is nearest 100 rounded, 4300 is not because you have to add extra 70 to get 4300, therefore instead you remove 30 to get 4200

simply I meant that 4200 is closer to 4230, therefore we take 4200 instead of 4300

similarly the same reason for I took 3600 as it is closer to 3590
