Suppose that the following group of values was entered into the tvm solver of a graphing calculator: n=240; i%=14.4; pv=85000; pmt=–1081.7751; fv=0; p/y=12; c/y=12; pmt: end. also suppose that the "bal(" function was used as follows: bal(48). which of these expressions is equivalent to the value returned by the "bal(" function?

answer: the answer is e

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
