-16.9x + 16 is the correct answer. You have to remove the parentheses, collect the like terms, and then simplify.
5 · (6 - 1) + 3
= 5·5 + 3
= 25 + 3
= 28
When i use " / " its the bar between, the divider.
X = - 2( 6 - iy - 3i ) / 3
Y = 3( x - 2i + 4 ) / 2i
You are told to ignore the amount of principal paid, so you are apparently to assume the loan amount was for $50 thousand.
a) The old monthly payment was $10.67×50 = $533.50
b) The new monthly payment is $11.72×50 = $586.00
c) The increase in monthly payment is figured in the usual way:
... (new/old -1)×100% = (1.0984-1)×100% = 9.84%
_____
In reality, about 3% of the loan will have been paid at the end of 2 years. Thus, the original loan amount may have been near $51,500. This problem is telling you to ignore the difference.
