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?

Respuesta :

Answer: 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

Answer:

$8/necklace

Step-by-step explanation:

Money spent total:

$40-$4= $36

Money spent on bracelets:

$4*3= $12

Money spent on necklaces:

$36-$12= $24

Money spent per necklace:

$24/3= $8
