A. Using your work from part (d) of problem 1-68, which pairs of angles are congruent? What other relationship do these angle pairs have? b. Based on your observations from part (a), write a conjecture. Remember that a conjecture is a statement based on incomplete evidence that is unproven.

Revenue will increase if price of mask is increased.

Step-by-step explanation:

The current price of the mask is $1 per mask and there is expected demand of 6000 masks per week. If the company plans to increase the price the demand for the masks will decrease.

Revenue  = 6000 * x

Total revenue will be  $6,000 if the price of mask is $1. If price of mask increase by 10% then quantity will be declined to 5850 masks [6000 - 150].

New price = $ 1 * 110% = $1.10

Revenue = 5850 masks * $ 1.10 = $6,435.
