Answer:

B. Alex smokes a pack of cigarettes per day even though he knows that he may face poor health down the road because of his smoking habit.

Step-by-step explanation:

Time preference means that the person would like to have temporary but instant satisfaction. In this case, B would be the best choice, for Alex wants to experience the "high" (I guess?) from smoking, even when he knew that there would be health consequences down the road.

In this case, it is not:

A, for Thomas is not going to receive his reward (a profit from the investment) until later on. The money he invest is still "there", but it is technically gone into investment.

C, because this is assuming that retirement is a long way off, and that this would be a long-term investment, rather than a short term.

D, this is a long-term investment, as Sarah "hopes" that she can earn it all back in the future. With what she learns, she, in the long run, wants to find a sustainable & high-paying job.

Al's Produce Stand sells 8 ears of corn for $2.25. Barbara's Produce Stand sells 12 ears of corn for $3.50. Write two equations,

Gennadij [26K]

Answer:

6n = 1.50

and

13n = 3.12

Step-by-step explanation:

Here in this question, we are interested in writing equations that relate the number of ears of corn sold and the cost.For Al’s produce stand, let the price per corn sold be n

Thus;

6 * n = 1.50

6n = $1.50 •••••••(i)

For the second;

let the price per corn sold be n;

13 * n = $3.12

-> 13n = 3.12 •••••••••(ii)

Katherine is considering two new cell phone plans. She doesn't want to spend more for minutes she won't use. One plan allows up

mojhsa [17]

Answer:

The first plan of $49 will be best plan for her.

Step-by-step explanation:

Katherine used 1479 minutes call in the last 6 months.

So, the average monthly call that Katherine made is $\frac{1479}{6} =246.5$ minutes.

Now, there are two plans for mobile recharge.

One is 250 minutes call time for $49 and the other is 350 minutes call time for $65.

Since 246.5 < 250 and Katherine does not want to spend more for minutes she won't use, then the first plan of $49 will be the best plan for her. (Answer)

Tina has been dieting for a total of 13 weeks she lost 3 pounds on the first week of her dad but gain back a pound on the second

natima [27]

So Tina has been dieting for 13 weeks

On week 1: She lost 3 pounds, so +3 pounds

On week 2: She gained a pound, so - 1 pound

On each remaining week, she lost 2 pounds, so,

On week 3: She lost 2 pounds, so +2 pounds

On week 4: She lost 2 pounds, so +2 pounds

On week 5: She lost 2 pounds, so +2 pounds

On week 6: She lost 2 pounds, so +2 pounds

And so on,,,

So losing 2 pounds each week for 11 weeks would equal, 2 pounds x 11 weeks = 22 pounds

So, add that all up: 3 pounds - 1 pound + (2 x 11 weeks) = 24 pounds total

Which is the slope-intercept form of the equation of a line that passes through (5,-4) and has a slope of 3/4

Andreas93 [3]

Y = mx +b whre m is the slope and b is the y-intercept.

We have the slope 3/4 so put that instead of m

y = 3/4x + b

Now to find the y-intercept (b), plug the ordered pair in and solve for b.

-4 = 3/4 * 5 + b
-4 = 15/4 + b
-31/4 + b

So y = 3/4x - 31/4
