It could be either y = 12.75x or y = 13x. Check if you made a typing error because these rates are both better than B
(n-21)/2=4n is the equation
First, divide what is in the parentheses by 2
0.5n-10.5=4n
Then, multiply the whole equation by 2 so we have all whole numbers
n-21=8n
Move N so that it is with 8n
7n=-21
Divide 21 by 7
n=-3
Solution: The number (n) is equal to -3
Anna had the biggest change in their bank account because they dropped by $48. The rest of the numbers are closer to zero while -48 is the furthest from zero, therefore it is the biggest change.
So this statement is caused for subtracting. So we have to subtract 6,700.00 from 3,995.00 and the answer would be 2705
Hope this helps :)
