A midwestern music competition awarded 38 ribbons. The number of blue ribbons awarded was 1 less than the number of white ribbon
Artist 52 [7]
Starting from what I know (the difference between ribbons), I decided to go from the bottom and work my way up. I then noticed a pattern (each sum was three more of the previous one), and decided to keep my pattern of the three numbers but not have to do any major mental work and instead add three to the previous sum until I got to 38.

Which statement lists contractionary policies? Question 73 options: a) The Fed purchases bonds, lowers the discount rate, and lo
Ne4ueva [31]

Answer:

The correct answer is letter B.

Step-by-step explanation:

Contractionary monetary policies are instruments used by the FED to decrease the amount of money in an economy. There are three classic instruments of monetary policy: open market, rediscount policy and compulsory deposit. The open market is about buying and selling federal government bonds. Thus, by selling bonds, the bank will be increasing the supply of bonds in the economy, on the other hand, is withdrawing dollars, that is, will be withdrawing currency from the economy, resulting in a contractionary monetary policy. Rediscount refers to the interest rate on loans that the FED lends to financial institutions. In situations of illiquidity, banks turn to the FED for loans. In this case, the FED, by increasing the rediscount rate, hindering the supply of money to the institutions and thus exerting a contractionary monetary policy. Finally, bank reserves refer to the part of banks' monetary reserves that are required to be deposited with the FED. Thus, by increasing the percentage of such reserves, the FED is exerting a contractionary fiscal policy, as it decreases the total amount of commercial banks' borrowing resources.

Delvig [45]

Answer: $8.60

Step-by-step explanation:

Let the price of a bread = x

Let the price of a tarts = x - 1

If 3 times the price of a loaf of bread is $29.5 more than half of the price of a box of tarts. This can be represented as:

3 × x = 1/2 × (1 - x) + 29.5

3x = 0.5 - 0.5x + 29.5

3x + 0.5x = 29.5 + 0.5

3.5x = 30

x = 30/3.5

x = 8.6
