A college student realized that he was spending too much money on fast food. For the remaining 5 months of the year his goal is to spend a mean of $50 a month towards fast food. How much can he spend in December, taking into consideration that in the other 4 months he spent $100, $25, $80, and $30, respectively? Round your answer to two decimal places, if necessary.

Answers

Answer:

The college student can spend $15.00 in December.

Step-by-step explanation:

This can be calculated as follows:

Let y represents the amount to spend in December.

The can now us the formula for calculating a mean is as follows:

Mean = Sum of montlhy spending / Number of months ...... (1)

From the question, we have:

Mean = $50

Sum of monthly spending = $100 + $25 + $80 + $30 + y = $235 + y

Number of months = 5

Substituting the values into equation (1) and solve for y, we have:

$50 = ($235 + y) / 5

$50 * 5 = $235 + y

$250 = $235 + y

$250 - $235 = y

$15.00 = y

Therefore, the college student can spend $15.00 in December.

Final answer:

To achieve a mean expenditure of $50 per month on fast food across 5 months, the student can only spend $15 in December, considering that he has already spent a total of $235 in the other 4 months. This keeps his total spending at $250, giving an average of $50 per month.

Explanation:

The student wants to spend a mean of $50 per month on fast food for 5 months. In 4 of those months, he has already spent $100, $25, $80, and $30, respectively. That totals to $235 in spent funds already. Since the goal is a $50 monthly average, we multiply $50 by 5 months to get a total desired spending of $250. To find out how much he can spend in December, we subtract the total already spent from the total desired spending. As such, he can spend $250 - $235, which equals to $15 in December.

Sure, let's calculate the answers for each of the given problems:

1) $7 + (-12) + (-3) = -8$

2) $2 + 8 + 7 + (-6) = 11$

3) $13 + 12 + 12 = 37$

4) $6 - 18 + 16 + (-12) + 5 = -3$

5) $24 + 19 + 5 + 3 = 51$

6) $-24 + 2 = -22$

7) $3.4 + 2.7 + 1.3 + (-1.2) = 6.2$

8) $7 + 7 + 7 = 21$

9) $-4 - 7 = -11$

10) $2 + 5 = 7$

11) $-2 + 6 = 4$

12) $-2 + 1 = -1$

13 ) $-15 - 4 = -19$

14) $7 - 19 = -12$

15) $5 + 20 = 25$

16) $-24 + 2 = -22$

17) $-2 + (-7) - 1 = -10$

18) $7 + 13 - 12 = 8$

19) $-15 + 3 - 8 = -20$

20) $-1 - 13 + (-17) = -31$

21) $-3 + 7 + 18 = 22$

22) $14 + 3 - 4 + 1 = 14$

23) $27 - 3 + (-24) = 0$

24) $(14 + 6) - (-5 - 13) = 38$

25) $10 - (5 + (-7) + 2) = 14$

26) $(-3 + 10) - ((5 - 8) + (-10)) = 10$

27) $(-4 + 2) + (-16 - 5) = -23$

28) $(27 + 6) + (-6) = 27$

29) $27 - (-6 + (-6)) = 39$

30) $(16 - 4) - (8 + 12) = -8$

Now, connecting the answers in order:

The value of the 2in 204.75 is how many times the value of the 2 in 103.52

Answers

Answer:

10000

Step-by-step explanation:

Given : Number :204.75

Number :103.52

To Find:The value of the 2 in 204.75 is how many times the value of the 2 in 103.52?

Solution:

Number :204.75

Value of 2 is 200

Number :103.52

Value of 2 = $(2)/(100)=0.02$

So, $10000 * 0.02 = 200$

Thus 10000 times of 0.02 is 200.

So, the value of the 2 in 204.75 is 10000 times the value of the 2 in 103.52.

I made it into an equation and took out all the other numbers so the equation would be 000.02x=200 and your trying to find x so you divide 200 by 000.02 equals 10000 and if you put it back in the equation 000.02(10000)=200 it comes out 200 so the answer is 10000
