Question

Can I get help on this problem showing my work?

Answer 1

9x+9+72

9x= total cost

9= shipping fee

72= what you paid in all

Answer 2

`cost \: of \: 1 \:bracelet \\(no\:shipping): \\72 \: dollars - 9 \: dollars \: shipping = \\ 63 \: / 9 \: = cost \: of \: 1 \: bracelet \: \\ = 7 \: dollars`

`\\cost \: of \: shipping: \\ 9 \: dollars \: / 9 \: bracelets \: = \\ 1 \: dollar\: per\:bracelet \\ \\ formula \: for \: cost \: overall: \\ 7y \: + y`

y = quantity, for example:

I want to buy 1 bracelet =
1×7 = 7 + 1 = 8$ per bracelet
