Answer: Jeremiah's answer was -91.
Step-by-step explanation:
Jeremiah's tutor gave him a math problem to solve.
Given problem: 546 ÷ − 6
Since 546 ÷ 6 = 91
Then, 546 ÷ − 6 = -(546 ÷ 6) = -91 [∵ In integers (a÷(-b))= (-a ÷b)= - (a÷b)]
If Jeremiah's answer was correct , then the answer would be -91.
Hence, Jeremiah's answer was -91.
The total amount of the increase was: 1230 - 1200 = 30
The percent increase is: 30/1200 = 0.025
0.025 x 100 = 2.5% increase
