The expression 8x + 2(3y) represents the total amount, in dollars, that Davellyn spent on tank tops and scarves, where x represe
nts the number of tank tops she bought and y represents the number of scarves she bought. Which statement must be true about the amount Davellyn spent? She spent 8x dollars on scarves.
She spent 8 dollars for each scarf.
She spent 6y dollars on scarves.
She spent a total of 14 dollars.
The question states that y represents the number of scarves she bought, so the first and second statements would be incorrect. You don't know how much she spent in total, so the fourth statement would also be wrong. So it's the third statement.
