Greg needs at least $1.60 in stamps to mail a package. He has 28 cents and 4 cent stamps. He can use no more than twenty 4 cent stamps as he only has one book left. a) write a system of linear inequalities to represent this situation, then graph.

b) using your graph, give two possible combinations of stamps that Greg can use to ensure he mails his package with the correct postage.

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
