And explain all the steps to the problem

So, 1725 would be 1 and a half month's pay of rent.

The equation would be 1725 divided by 1.5 since that would get us what the two friends paid for one month of rent. Let r= rent.

1725/1.5= r

1725/1.5= 1150

So, rent would equal $1150.

I hope this helps!

B. 137.32 cm3

Step-by-step explanation:

So what we know is that

Height = 12

Diameter is 6 which would make the radius 3.

The current volume is 339.12

12cm × 1.12 = 12.44 (This is the new height.)

3cm × 1.12 = 3.36 9 (This is the new radius)

Volume of future can (V2) = πr²h = 3.14 × 3.36 ×3.36 × 13.44 = 476.43

Then you would subtract  476.43(new volume) - 339.12(old volume) = 137.31

That would round to 137.32 cm3.

So the answer is B. 137.32 cm3.
