Answer:
718
Step-by-step explanation:
It can be done this way:
4% of 50.0 is 2.0
4% of 900 is 36
4% of 7000 is 280
4% of 10,000 is 400
add them all up and we have:
400 + 280 + 36 + 2 = 600 + 110 + 8 = 718
The option A and B would be wrong since it was less than the minimum value of the function. To find the cost, you just need to replace the x variable with time after 2005.
If the time is 2025 it will be
x= 2025-2005= 20
y = 15.7x + 459
y = 15.7(20) + 459
y = 314+ 459 = <span>$773.00
</span>
If the time is 2030 it will be
x= 2030-2005= 25
<span>y = 15.7x + 459
</span><span>y = 15.7(25) + 459
</span>y = 392.5+ 459 =<span>$851.50</span><span>
</span>
Answer:
Again, pretty sure its (-1,-2)
Step-by-step explanation:
<span>-9=2n
n = -9/2 = -4.5</span>
