A market supply curve has three prices — $6.50, $7.00 and $7.50 — with a quantity supplied of 7 tonnes at the price of $6.50, 9 tonnes at $7.00, and 11 tonnes at $7.50. a. Is this supply curve a straight line? multiple choice 1 This curve is a straight line because it has a constant slope of 0.5. This curve is not a straight line because it does not have a constant slope. This curve is a straight line because it has a constant slope of 1. This curve is a straight line because it has a constant slope of 0.25.

a. Is this supply curve a straight line?
multiple choice 1
-
This curve is a straight line because it has a constant slope of 0.5.
-
This curve is not a straight line because it does not have a constant slope.
-
This curve is a straight line because it has a constant slope of 1.
-
This curve is a straight line because it has a constant slope of 0.25.
b. What is the price elasticity of supply, es, between prices $6.50 and $7.00 and between prices $7.00 and $7.50? Do not round your interim calculations before obtaining the final solution (i.e. do not clear your calculator). In each case, express the number to two decimal places and do not include a positive or negative sign (i.e. 1.67, not -1.7 or +1.667).
The price elasticity of supply is between prices $6.50 and $7.00, and is between prices $7.00 and $7.50.
c. Based on your answers to parts (a) and (b), must a supply curve with a constant slope have a constant numerical elasticity?
multiple choice 2
-
A supply curve whose slope varies has a supply elasticity which varies by exactly the same proportions.
-
A supply curve with a constant slope does not need to have a constant elasticity.
-
A supply curve with a constant slope must have a constant supply elasticity.
-
A supply curve whose slope varies must have a constant supply elasticity.
