Ashley charges $6 for a bracelet and 12$ for a necklace. She earned $168. Use b for bracelets and n for necklaces, and write an equation for this situation. Then solve it for b.

Step-by-step explanation:

let the number of bracelet be b

Let the number of necklace be n

If Ashley charges $6 for a bracelet , the total amount charged for b bracelets will be 6b

If she charge $12 for a necklace, the total amount for n necklace will be 12n

If she earned $168 in total, then:

6b + 12n = 168

Divide through by 6

b + 2n = 28

Hence the equation for this situation is b + 2n = 28

Next is to solve for b:

Make b the subject of the formula:

b + 2n = 28

subtract 2n from both sides

b + 2n - 2n = 28 - 2n

b = 28 -2n

Hence the function for b will  be b = 28-2n

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
