For Q1, you have to set these equations equal to each other because it is asking how much of x is necessary to make the same amount of y, so:
3995 + 225.50x = 6500 + 100.25x
solve for x:, and get x=20
so 20 tons of sugar will give the companies the same cost.
For Q2: you need to plug in x=20 into either one of the original equations, and solve for y because this will give you the cost of transportation, so:
y= 3995 + 225.50(20)
y=$8,505 for the total cost
Answer:
profit will come while selling book
Use this equation: 102/300=x
x*100=the answer
for quicker reference: the answer is: the baseball player hit the ball 34% of the times he was at bat
Total cost for the trip = $800.
Let x = original number of friends.
Therefore the equally shared cost of the trip for each friend is $800/x.
After 2 friends drop out, the cost for each friend increases to $800/(x-2).
The increase in cost for each remaining friend is $20, therefore

Divide through by 20.

Cross multiply.
x(x - 2) = 80
x² - 2x - 80 = 0
(x + 8)(x - 10) = 0
x = -8 or 10
Reject x = -8 because we cannot have a negative number for friends.
x = 10
Answer: There were 10 friends in the original group.
Answer:
Menu Costs
Explanation:
From the question we are informed about Gilberto who manages a grocery store in a country experiencing a high rate of inflation. To keep up with inflation, he spends a lot of time every day updating the prices, printing new price tags, and sending out newspaper inserts advertising the new prices. His employees regularly deal with customer annoyance over the frequent price changes. This case is an example of the of Menu Costs inflation.
In domain of economics, menu cost can be regarded as the cost to a firm that results due to changing its prices. When there is high inflation, firms needs to often make a change to their prices ,so they can keep up with economy-wide changes. The name arised out of the cost of a printing new menus of a restaurants , but it is used by economists when they are generally referring to the costs of changing nominal prices
