Answer:
A. 0.80
Step-by-step explanation:
First, you need to find the mean of the cost of Sara's lunches the first week. The mean is the 'average,' and to find the average, add all of your terms and divide by the amount of terms.
Sarah's total cost for the first week was $47.49. Divide by your number of terms (5) for your average daily cost.
This can be rounded to $9.50.
For the next week, Sara spent $4 more in total than the first week. So, add $4 to your total.
Now, divide $51.49 by your number of terms (5) again to find your average for the second week.
This can be rounded to $10.30.
Find the difference.
Sara spent $0.80 more on average.
Answer:
A(x) = $80 - ($4.50/lunch)x
Step-by-step explanation:
The amount Jordyn has remaining in her lunch account, as a function of the number of days on which she bought lunch, is given by
A(x) = $80 - ($4.50/lunch)x, where x is the number of lunches purchased.
So we know that
Year 1 = $55,000
Year 2 = 55000 + (55,000 x .04) = 55000 + 2200 = $57,200
Year 3 = 57200 + (57200 * .04) = 57200 + 2288 = $59,488
Year 4 = 59488 + (59488 * .04) = 59488 + 2379.52 = $61,867.52
Year 5 = 61867.52 + (61867.52 * .04) = 61867.52 + 2474.70 = $64,342.22
Year 6 = 64342.22 + (64342.22 * .04) = 64342.22 + 2573.69 = $66,915.91
Year 7 = 66915.91 + (66915.91 * .04) = 66915.91 + 2676.63 = $69,592.54
Year 8 = 69592.54 + (69592.54 * .04) = 69592.54 + 2783.70 = $72,376.24
Year 9 = 72376.24 + (72376.24 * .04) = 72376.24 + 2895.05 = $75,271.29
Year 10 = 75271.29 + (75271.29 * .04) = 75271.29 + 3010.85 = $78,282.14
So by the tenth year following graduation, the student would be making $78,282.14 a year. If you add up all of the values (Year 1 thru Year 10) you get a total income over ten years of $660,355.86
Answer:
180
Step-by-step explanation:
A negative by negative is positive. So, you can pretend that the numbers are 6 and 30. Product means the answer for multiplication. In this case, product of 6 and 30 is 180. The product of -6 and -30 is 180.
Therefore, the answer is 180.
