Are there any answer choice
1/15
1/3 chance of getting elf, 1/5 chance of getting magic so the chance of getting both is 1/3x1/5=1/15
Set up the equation like this
4,275= x (1.025)∧18
then solve for the answer
The answer should be $2740.98, but you should double check.
From principle of floatation:
W = U
The volume of water displaced is as a result of the volume of object submerged.
The wood would also float with 1/4 of its total height or total volume below the water surface.
