874.6

Step-by-step explanation

Profit = Sales - Costs

Profits by day:

Mon:

225 - (225*0.12) -9 = 189.0

Tue

260 - (260*0.12) -9 = 219.9

Wed

230 - (230*0.12)-9 = 193.4

Thu

180 - (180*0.12) - 9 = 149.4

Fri

150 - (150*0.12) -9 = 123.0

Total:

189+219.9+193.4+149.4+123 = 874.6

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.
