Suppose there is currently a tax of $50 per ticket on airline tickets. Sellers of airline tickets are required to pay the tax to the government. If the tax is reduced from $50 per ticket to $30 per ticket, then thea. demand curve will shift upward by $20, and the price paid by buyers will decrease by less than $20.b. demand curve will shift upward by $20, and the price paid by buyers will decrease by $20.c. supply curve will shift downward by $20, and the effective price received by sellers will increase by less than $20.d. supply curve will shift downward by $20, and the effective price received by sellers will increase by $20.

the demand curve will shift upward by $20 and the price paid by buyers will decrease by $20.

Step-by-step explanation:

the reduction in the fixed amount of tax from $50 t0 $30 will bring about reduction  of $20 in the price of ticket. the reduction in the price of the ticket, other factors held constant, will brings about change in the demand curve.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
