A student has a savings account earning 9% simple interest. She must pay $1400 for first-semester tuition by September 1 and $14
IRINA_888 [86]

Answer: The answer is $2,759.22

Explanation: From the question above, we have:

September 1st to January 1st is 4 months, this is 1/3 of a year which means that the student will earn:

=> 9/3 = 3%

3% interest for the money that is saved is the savings account. So the student must put in at least:

x + 3%x = 1400

x + 0.03x = 1400

1.03x = 1400

x = 1400 / 1.03

x = 1,359.22

Therefore, if the student saves $1,359.22 in the savings account By September 1st, she will have $1400 by January 1st.

Also, the student needs to make $1400 for the first semester. So overall she will need to make:

1,400 + 1,359.22 = $2,759.22 during the summer in order to ensure that she will have enough money to pay for both semesters.

artcher [175]

The eco-nomy was in long-run equilibrium when aggre-gate demand increased. At this point in time, the expec-ted inflation has start-ed to adjust to the new high-er actual inflation rate. Accor-ding to the (Friedman) natural rate the-ory, this means the unemploy-ment rate in the economy must curr-ently be <u><em>below the natu-ral rate</em></u>.

Milton Friedman defi-ned the natural rate of unemploy-ment as the level of unemployment that result-ed from real economic forces, the long-run level of whi-ch could not be altered by monet-ary policy. Accor-ding to the general equili-brium model of economics, natural unemploy-ment is equal to the level of unemploy-ment of a labor mark-et at perfect equilibrium.
