Let
be the most the manager can pay the suppliers.
Then, we know from the information given in the question that the manager needs a 30% markup based on cost.
Therefore, the guiding equation will be:

because $10 is the most people will pay for a neck warmer.
Thus, the above equation will become:




Thus, the most a manager can pay the suppliers for neck warmers and still keep the selling price at $10 is $7.69
A half-life of 9 minutes corresponds to a decay factor <em>k</em> such that

Then the time it takes for the substance to decay from 610 g to 124 g is time <em>t </em>such that

Solve for <em>t</em> :



so it takes about 20.7 min for the 610 g sample to decay down to 124 g.
Answer:
m∠B = 70.0° (nearest tenth)
Step-by-step explanation:
<u>Sine Rule for Angles</u>

(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Given:
Substituting the given values into the formula to find m∠C:




Interior angles of a triangle sum to 180°



Therefore, m∠B = 70.0° (nearest tenth)
