Answer: E. N1.10
<u>Step-by-step explanation:</u>
18 words cost a total of 35k
48 - 18 = 30 additional words cost 2.5k each: 30 × 2.5 = 75k
35k + 75k = 110k
= N1.10
Let's actually find the sol'n set.
<span>Line A: 2x + 2y = 8
Line B: x + y = 4
becomes
</span><span> 2x + 2y = 8
x + y = 4
------------------ Multiply the 2nd equation by -2, obtaining -2x - 2y = -8,
and then add your result to the first equation:
</span> 2x + 2y = 8
-2x - 2y = -8
------------------- Combine all 3 columns.
0 + 0 = 0
0 always = 0, so there are infinitely many solutions to this system.
Step-by-step explanation:
Let P be price after t year . From the formula of compounding
P = 9 (1.015)^t
Taking log to the base e on both sides
ln P = ln 9 + t ln 1.015
= (2.197 + .0149t )
P = e^{(2.197+.0149t)}
