£/$340
25% is 1 over 4 and that gives us divide by 4
So what you want to do here is divide 340 by 4 which gives us £/$85
You save around 85 if I’m correct please tell me if I’m wrong :)

Sometimes you have to be careful with the domain and range of the composite function.

Answer:
I disagree with Luis's claim. While 8*3=24, 8^3 is 512mm. Which is 488mm more than 24mm.
201 inches.
Step-by-step explanation:
They use the expression s^3 to find the volume of plastic to make each cube. Luis says that if s=8, then the volume is 24 cubic mm. I disagree with Luis's claim. While 8*3=24, 8^3 is 512mm. Which is 488mm more than 24mm.

Part A
Blue: 3ft - 36in
Red: 60in - 5ft
Yellow: 2.5ft - 30in
Green: 12ft - 144in
Purple: 240in - 20ft
Part B
1 foot = 12 inches
16.75ft = 201in
I'm not sure how to do the expression
but if 1 foot = 12 inches, and you substitute 16.75 for a foot, then you have 201 inches.
