Which system of equations best represents the situation above?

Note: In all of the choices below, e represents money earned, p represents price, and n represents number of items sold.

a
Earrings: e=6(30-n)
Necklaces: 264.50-e=12.50*n

b
Earrings: e=12.50(30-n)
Necklaces: 264.50-e=6*n

c
Earrings: e=6(n-30)
Necklaces: e-264.50=12.50*n

d
Earrings: e=30-n
Necklaces: 264.50-e=n

mary works for a commission of 12% on all goods she sell for the month if her basic salary is 3000 per month and she sells $2500
SOVA2 [1]

Answer:

3300

Step-by-step explanation:

Formula

Gross Salary = Basic + Commission

Givens

Basic = 3000

% = 12%

Solution

Gross = 3000 + 12/100 * 2500

Gross = 3000 + 30000/100

Gross = 3000 + 300

Gross = 3300

PLS help I will give brainliest to the one who will answer me first.<br><br> pic is not blurry

Answer:

mean for a = 60/10 = 6

mad of a = 2

mean for b = 80/10 = 8

mad of b = 2

Step-by-step explanation:

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. The mean absolute deviation, MAD, is 2.

\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|

m(X) = average value of the data set

n = number of data values

x_i = data values in the set

mean = average.
