$7.00
$8.33
$12.00
$21.00

$7

Step-by-step explanation:

Rebecca and Megan are shopping at a store which sells jewelry, scarves, and purses. Megan buys 3 bracelets and 3 necklaces. One bracelet costs $5 and Megan pays the clerk $40 and gets $4 change.

From the question, since Megan pays $40 and collects $4 change, then the total cost is $40-$4 = $36.

Let the bracelets be denoted by b and necklace be denoted by n. Since Megan buys 3 bracelets and 3 necklaces, bracelet is $5 and total cost is $36. This will be:

3b + 3n = 36

3(5) + 3n = 36

15 + 3n = 36

3n = 36 - 15

3n = 21

n = 21/3

n = 7

A necklace costs $7.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.
