Aman realizes he lost the detailed receipt from the store and only has the credit card receipt with the after-tax total. if the after-tax total was $972.00, and the tax rate in the area is 8%, what was the pre-tax subtotal?

$972.00/1.08 = Total pre-tax was $900

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer: '

the distance between points l and m
