10.During the time of COVID – 19 pandemic Matt wanted to know the
difference between the 1823 infected persons from the 485 who
recovered from the virus. He wanted to work on this as fast as he can
be unfortunately, he did not have a calculator. So, he worked out the
answer as follows:
1823 – 485 1
= 1823 – (500 – 15) 2
= (1823 – 500) – 15 3
= 1323 – 15 4
= 1308 5
Matt’s friend, Rico, told him that his answer was wrong, and the correct
answer should be 1338. Which step makes Matt’s work wrong?
A. 2
B. 3
C. 4
D. 5
