-2 1/2 ÷ 3 1/2 =
I need help with this answer ​

Answers

Answer 1
Answer: So if you make them improper fractions the -2 1/2 would turn into -5/2 and the 3 1/2 would turn into 7/2. If you do a multiplicative inverse to the 7/2 that makes the equation
-5/2 x 2/7
-5 x 2= -10
2 x 7=14
So you would have -10/14
You can simplify -10/14 into -5/7 and that’s your answer

You pay $2.40 for 3434 pound of grapes. Your friend buys a pound of grapes at the same time and estimates that he will pay $1.80. What can you say about your friend's estimate?

Answers

If your friend was working from your figures, then his estimate was
waaaay off, like in outer space.

If you paid $2.40 for 3434 pounds, then that works out to something
like 0.007¢ for each pound.  His estimate of $1.80 is more than 2,500
times as much as you paid for each pound. 

Even allowing some slack for the quantity discount that you surely
must have been awarded for buying 1.7 tons of them all at once, still
that doesn't support his wild estimate in any way. 

He'd be better off buying a few pounds from you, at, say, 50¢ a pound. 
He needzum, you gottum, he'll gettum, and you'll  never missum.  That way,
you'll both make a killing, and it's a win-win-win all around.

Find the total profit or loss for each color of T-shirt.

Answers

He experiences a gain of 27 from the two more movies, resulting in a net utility gain of 7. In other words, José might feel happier with the two movies instead of the fourth T-shirt.

To find the total profit or loss for each color of T-shirt, you need to analyze the given expenditures and gain.

Let's assume the fourth T-shirt to which José gives up was of a particular color.

According to the information, this step frees up $14. José spends that money to buy the first two movies at the cost of $7 each. Therein exists the loss or gains.

Based on Table 6.2, the marginal utility of the fourth T-shirt, i.e., the satisfaction José gets from it, is determined to be 18 utils.

By giving up this T-shirt, he experiences a utility loss of 18 utils.

In comparison, he experiences a gain of 27 from the two more movies, resulting in a net utility gain of 7.

In other words, José might feel happier with the two movies instead of the fourth T-shirt.

Thus, the total profit or loss for the color of the T-shirt that was given up would be calculated based on the difference in utility gained from the two cases.
