The cost of 3 scarves in $24.75. What is the unit price?

$8.25 for 1 scarf

All you have to do is divide the number($24.75) by the amount of scarves(3)

So divide 24.75 divide by 3 is 8.25

Please mark branliest if this helped

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.
