Josh had zero melons because he never got any .
Yes because $18 divided by 3 bracelets makes the price per bracelet $6. $30 divided by 5 bracelets makes the price per bracelet $6. The cost per bracelet is the same so the cost to bracelet ratio is the same and both are a $6 to 1 bracelet ratio
I would go with A but I am not 100% sure so you may want to check however you can.
132 x 14.1% = 18.612
So 18.612 rounded to 18.6
