Answer:
$1,101.32
Explanation:
Simple interest accounts balances are calculated using the following formula
A = P ( 1 + rt)
where:
A = final account balance
P = starting balance
r = interest rate (annually) percentage divided by 100
t = years
Therefore, we can plug in the values provided in this formula and solve for P which would be the amount that Kremena needs to deposit.
1,250 = P ( 1 + (0.045 * 3))
1,250 = P * 1.135 ... divide both sides by 1.135
1,101.32 = P
Finally, we can see that Kremena would need to deposit a total of $1,101.32 to have the amount that she wants after 3 years.
Answer:price elasticity of demand for Dunkin Donuts’ regular coffee is 1.8
Explanation: Using the midpoint formnulae
Price elasticity of Demand =percentage change in quantity demanded/ Percentage change in price.
Percentage change in quantity = new quantity - old quantity / (new quantity + old quantity)/2 x 100
= 40-10/(40+10)/ 2 = 30 /25 = 1.2 x 100 =120%
Percentage change in price = new price - old price / new price + old price)/2 x 100
= 1- 2 / (1+2)/2= -1/1.5x 100 = -66.67 %
Price elasticity of Demand =percentage change in quantity demanded/ Percentage change in price.
= 120%/-66.67%= -1.79 = -1.8
For Price elasticity of demand, the sign is not included and the basis for elasticity is on the value itself . here we can conclude that the Price elasticity of demand for Dunkin donut is 1.8 and elastic because a fall in price led to an increase in amount being sold.
Answer:
D
Explanation:
B and C dont make sense A is that you can never run out of things in stock
Answer:
<em>The answer is 17.01 minutes</em>
Explanation:
<em>Given that:</em>
<em>The learning rate (r) = 85% = 0.85</em>
<em> T₃₂= 23.52 minutes</em>
<em>By applying the learning curve formula</em>
<em>Thus,</em>
<em>Tₙ = T₁ nᵇ</em>
<em>Where b represent ln(r)/ln2</em>
<em>b = ln( 0.85)/ln2 = -0.2344</em>
<em>23.55 = T₁ * (32)^-0.2344</em>
<em>T₁ = 23.55 * (32)^0.2344</em>
<em>Now,</em>
<em>T₁₂₈ = T₁ (128)^ - 0.2344</em>
<em>= 23.55 * (32)^0.2344 * (128)^ - 0.2344</em>
<em>=17.01 minutes</em>
