Answer:Number of 8 cent stamp =9

Number of 41 cent stamp = 5

Explanation: Explanation: Let x= number of 41 cent stamp

Let y= number of 8 cent stamp

Total postage fee =$2. 77 = 277cent

Combining both, we have:

41x + 8y = 277

We can vary or iterate the value of x using different integer values to find y(must also be an integer) as the number of stamps can't be decimal.

If y=1

41x + 8 = 277, x =6.56(not possible)

If y=2

41x + 16 = 277, x =6.365(impossible)

If y=3

41x + 24 = 277, x =6.17(impossible)

If y=4

41x + 32 = 277, x=5.98(impossible)

If y=5

41x + 40 = 277, x=5.78(impossible)

If y=6

41x + 48 = 277, x= 5.58(impossible)

If y=7

41x + 56 = 277, x=5.39(impossible)

If y=8

41x +64 = 277, x=5.20(impossible)

If y=9

41x + 72 = 277, x=5.

At this point its safe to conclude that y = 9, x = 5

Number of 8 cent stamp = 9

Number of 41 cent stamp = 5

If a shortage exists in a market, the natural tendency is for:

ASHA 777 [7]

A shortage in the marketing occurs if the quantity demanded is larger than the quantity supplied. If a shortage exists in a market, the natural tendency is for the price to increase. Gas is a great example if price increases when there is a shortage within the market. Whenever there is a shortage in gas we often see the price of gas driving upwards of cents to dollars more per gallon. This happens because the market is aware that even with the increase in price, people still need purchase gas to live daily life. Therefore, as it's rising in price, people are still purchasing and likely it will keep climbing for a little while.
