A boy owns 8 pairs of pants, 9 shirts, 2 ties, and 5 jackets. (a) How many outfits can he wear to school if he must wear one of each item? Correct = 720 (b) How many outfits can he wear to school if he must wear pants, shirt and a jacket, but the tie is optional?

can you put the picture up?

step-by-step explanation:

not sure but it may be b, as i said i'm not sure.

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
