The total money earned if Lee sold four scarves at twenty dollars each.

$80

Step-by-step explanation:

If we have four scarves, and each costs $20, we can multiply these two numbers to find the total profit made.

2 times 4 is 8, and adding a 0 to that is 80.

Hope this helped!

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
