Tammy completed 12 jobs.

<h3>What is the substitution method?</h3>

The algebraic approach to solving simultaneous linear equations is known as the substitution method.  in this procedure, The value of one variable from one equation is substituted in the second equation.

Given Susanne(S) did 10 jobs, and three girls together did 28 jobs Tammy(T) works twice as fast as Martha(M).

Since the girls each worked for two hours, this indicates that Tammy worked twice as much or held twice as many jobs.

T = 2M    ........................equation (1)

M + S + T = 28 ........................equation(2)

S = 10 ..................................equation(3)

By solving the above equation, we get:

Martha(M) = 6

Tammy(T) = 12

Hence, Tammy completed 12 jobs.

In the short run, a supply shock will _________ the equilibrium level of prices and ___________ the equilibrium level output. re
Taya2010 [7]

Answer: raise; reduce

Explanation:

A Supply shock is described as a situation where the supply of a good changes suddenly/ abruptly due to an unforeseen event.

Supply shocks can be positive but are usually negative so we will assume the supply shock is negative here.

If there is a negative supply shock, the amount of goods being produced will reduce abruptly which will force the supply curve to shift left.

It will then intercept the the demand curve at an equilibrium level that has a higher price and a lower quantity of output.

Think of it this way. Negative supply shock ⇒ less goods ⇒ scarcity ⇒ higher prices.

Henry Crouch's law office has traditionally ordered ink refills 55 units at a time. The firm estimates that carrying cost is 40%
defon

Answer:

Its action would be optimal given an ordering cost of $28.31 per order

Explanation:

According to the given data we have the following:

economic order quantity, EOQ= 55 units

annual demand, D=235

holding cost per one unit per year, H=40%×$11=$4.4

ordering cost, S=?

In order to calculate the ordering cost we would have to use the following formula:

EOQ=√(<u>2×D×S)</u>

                (H)

Hence, S=<u>(EOQ)∧2×H</u>

                     2×D

           S=<u>(55)∧2×4.4</u>

                   2×235

          S=<u>13,310</u>

                470

          S=$28.31

Its action would be optimal given an ordering cost of $28.31 per order

You currently have $5,400. First United Bank will pay you an annual interest rate of 8.9, while Second National Bank will pay yo
IRISSAK [1]

Answer:

Second National  Bank

Present value (PV) = $5,400

Future value (FV) = $13,900

Interest rate (r) = 10% = 0.10

FV = PV(1 + r)n

$13,900 = $5,400(1 + 0.10)n    

<u>$13,900</u> = (1.10)n

$5,400            

2.574074074 = (1.10)n

Log 2.574074074 = n  log 1.10

<u>Log 2.574074074</u> = n  

Log 1.10                  

n =  9.9 years      

None of the answers is correct                                                                                                                                                          

Explanation:

In this case, we will apply the formula of future value of a lump sum. The present value, interest rate and future value were provided with  the exception of number of years. Thus, the number of years becomes the subject of the formula. The future value equals present value, multiplied                     by 1 plus interest rate, raised to power number of years.
