The expression 8x+2(3y) represents the total amount, in dollars, that davellyn spent on tank tops and scarves, where x represents 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

C. She spent 6y dollars on scarves.

Step-by-step explanation:

Let x be the number of tank tops and y represents the number of scarves bought by Davellyn.

We have been given an expression , which represents the total amount, in dollars, that Davellyn spent on tank tops and scarves.

Since x represents the number of tank tops, so 8x represents the amount spent on x tank tops costing each top $8.

Since y represents the number of scarves, so 3y represents the amount spent on y scarves. As 3y is multiplied by 2, so the cost of y scarves will be 6y (2*3y).

Therefore, Davellyn spent 6y dollars on y scarves and option C is the correct choice.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
