Rebecca and Megan are shopping at a store that sells jewelry, scarves, and purses. The cost of all the items at the store include tax. Megan buys 3 bracelets and 3 necklaces. Each bracelet costs $4. Megan pays the clerk $40 and gets $4 change. What is the cost, in dollars, one necklace?

the cost of each necklace is $8

Step-by-step explanation:

Let x represent the cost of each necklace.

Megan buys 3 bracelets and 3 necklaces. If each bracelet costs $4, it means that the total amount that she would pay for 3 bracelets and 3 necklaces is

(3 × 4) + (3 × x)

= 12 + 3x

Megan pays the clerk $40 and gets $4 change. It means that the total cost of her purchase is

40 - 4 = $36

Therefore,

12 + 3x = 36

3x = 36 - 12

3x = 24

x = 24/3

x = 8

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
