c. wages and prices are often inflexible in the downward direction

Explanation:

While the prices of the products can decrease in a recession when there is a decrease in demand there is an excess in the supply, therefore, the price decreases but, in real life that doesn't occur people prefer not to work rather than going to work for a lesser amount most of the times. The same goes for some prices under which the producer or manufacture firm does not reduce the price.

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"
