Design a combinational logic circuit that converts a 4 bit sign-magnitude number to the corresponding 4 bit 2's complement representation. write down the minimized expressions for a+,b+,c+ and d+ in order. a and a+ represent sign bit; b and b+, c and c+ and d and d+ represent magnitude bits from the most-significant bit to the least significant bit in each of their representation (sign bit-magnitude and twos' complement respectively).

The supply of higher education is highly price inelastic and demand has increased substantially.

Explanation:

The option that best explains the significant increases in the equilibrium prices for higher education in the United States since the 1980s is that the supply of higher education is highly price inelastic and demand has increased substantially.

Price inelastic means that a change in price has little effect on the demand for education and since there has been an increase in the demand for education, the suppliers will increase the price which led to the increase in equilibrium price.
