month | expenditure



september | $1,988.00

october | 2,234.50

november | 2,099.00

a) 1,999.00

b) 2,107.17

c) 2,234.50

d) 2,300.90

B = 2107.7

Step-by-step explanation:

An average number is a single number taken as a representative of a list of numbers which is usually the central value in a data set. Often average refers to the ‘arithmetic mean’, the sum of the numbers divided by how many numbers are being averaged, or the sum of the terms divided by the number of terms

Calculated by dividing the sum of the values in the set by their number.

Total Number of Months = 3

Combined Expenditure of all 3 months = Expenditure of September + Expenditure of October + Expenditure of November

Expenditure of 3 months combined = 1988 + 2234.5 + 2099 = $6321.5

The ‘Average’ expenditure would be equal to the sum of the expenditure of all three months divided by the number of months

Average Monthly = Expenditure of all months/ Total Number of months

Average Monthly Expenditure = 6321.5/3 = 2107.166667 = $2107.17

Hence answer is B

answer is:

1.75 pounds

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
