Answer:

  -7

Step-by-step explanation:

To find the differences in a sequence, subtract the term before:

  -15 -(-8) = -7

  -22 -(-15) = -7

These differences are the same, so constitute the "common" difference.

The common difference of the sequence is -7.

Nathan deposited 7/9 of his allowance into his savings account. He spent the remaining amount, or $2.50. How much did Nathan dep
kati45 [8]
Let us assume that total amount of Nathan's allowance = x
Amount of money deposited by Nathan into his savings account = 7x/9
Remaining amount that Nathan spent = $2.50
Now we have to get to the equation for solving the question asked.
7x/9 + 2.50 = x
7x + (9 * 2.50) = 9x
7x + 22.50 = 9x
22.50 = 9x - 7x
22.50 =2x
x = 22.50/2
   = 11.25
So $11.25 is the total allowance of Nathan.
Then The amount of money deposited by
Nathan in savings account = (7/9) * 11.25
                                           = 78.75/9
                                           = 8.75
So Nathan deposits $8.75 in his savings account.

Given a consumption function of c = $25 + 0.75yd, the average propensity to consume equals 1 when disposable income equals
Sphinxa [80]

Answer: Disposable income = $100.

Explanation:

Since we have given that

C=\$25+0.75Y

And, average propensity to consume = 1

i.e. APC = 1

As we know the formula of APC ,

APC=\frac{C}{Y}=1\\\\\implies C=Y

So, our equation becomes,

Y=\$25+0.75Y\\\\Y-0.75Y=\$25\\\\0.25Y=\$25\\\\y=\frac{25}{0.25}\\\\Y=100

Hence, Disposable income = $100.
