An isoquant is a curve that shows
a. all the combinations of inputs that yield the same total output.
b. all the combinations of inputs that cost the same total amount.
c. all the output levels that can be produced from a given set of inputs.
d. the optimal combination of inputs to use to produce any given level of output.

A. all the combinations of inputs that yield the same total output. 

Explanation:

An isoquant is a negatively sloped curve that shows all the combinations of inputs that yield the same total output. 

all of them make sense but, i would have to say ask someone who has been there/or lives there, and/or read recent newspapers from that city.

hope this !

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
