About 68% will make between $200000 and $240000.
Step-by-step explanation:
C. About 68% will make between $200000 and $240000. If the standard deviation is $18,000, then add that to $225000. That equals $243000. Subtract $18000 from the average, you end up with $207000. So it is close, but about 68% will make between $200000 and $240000.

y = -x/4 - 3
Step-by-step explanation:
y = -4x - 12 //Change and solve for y
