Zachary used the calculations shown to find how much he would spend on 16 ounces of pistachios.

6 ounces of pistachios cost $7.50
StartFraction 7 dollars and 50 cents Over 6 ounces EndFraction = StartFraction dollar-sign question mark Over 1 ounce EndFraction
Unit price = $0.80 per ounce
(16 ounces) (StartFraction 80 cents Over 1 ounce EndFraction) = 12 dollars and 80 cents

What was his first error?

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  

x

2  

x

​    

=240

=48
