Answer:
Net profit= $156,354
Step-by-step explanation:
Giving the following information:
A furniture company sells a desk for $1,435. It cost the company $817 to make the desk. Last month, 253 desks were sold.
<u>To calculate the net profit, we need to use the following formula:</u>
Net profit= number of units sold*(selling price - unitary cost)
Net profit= 253*(1,435 - 817)
Net profit= $156,354
Answer:
20°
Step-by-step explanation:
ΔCAD
BD=CD
∠BCD=50°, ∠BAD= 30°, x= ?
------------
BD=CD ⇒ ∠CBD= ∠BCD= 50° ⇒ ∠BDC= 180°- 50°×2= 80°
∠ADC= 180° - (50°+30°)= 100°
x= ∠ADC - ∠BDC= 100° - 80°= 20°
x= 20°
Step-by-step explanation:
P(rain and flight delayed) = P(rain) x P(flight delayed) = 0.07 x 0.19
= 0.013 (nearest thousandth)
