Eight and six tenths in decimal form is 8.6
1. Did it mentally think it’s 16. Make sure to yield to order of operations.
2. Because none of the operations are multiplication or division, parenthesis can be put anywhere that isn’t between exponents and it will yield 22.
I think the answer is the second one. A reflection over the x-axis and the a 90° counterclockwise rotation about the origin.
Answer: 2526 dollars
=============================
Work Shown:
Plug n = 400,000 into the function and simplify
f(n) = 939 + 5.29*(n-100,000)/(1,000)
f(400,000) = 939 + 5.29*(400,000-100,000)/(1,000)
f(400,000) = 939 + 5.29*(300,000)/(1,000)
f(400,000) = 939 + 5.29*(300)
f(400,000) = 939 + 1,587
f(400,000) = 2526
