Answer 1

Answer:

The only true statement is the total number of items needed is 12.

Step-by-step explanation:

Ms. Waters is bringing the centerpieces for the end of the year banquet and plans on using candles and vases. She spends $50 in total.

The system that can be used to represent her situation is given, where x represents the number of candles purchased and y represents  the number of vases purchased as

3x + 5y = 50 and  

x + y = 12.

Therefore, the cost of each vase is $5, not $3.

The cost of each candle is $3, not $5.

And the total number of items needed is 12, not 8.  

So, the only true statement is the total number of items needed is 12. (Answer)
