Answer 2

To find out how many wax warmers she will make when she makes 77 candles, we need to determine the missing value in the table.

The ratio of candles to wax warmers is 7:5, 14:10, 21:15, 28:20, 77:x.

We can simplify the ratio by dividing each side by its greatest common factor:

7:5 can be divided by 2 to get 7/2:5/2
14:10 can be divided by 2 to get 7:5
21:15 can be divided by 3 to get 7:5
28:20 can be divided by 4 to get 7:5
Therefore, the missing value must be 55, since 77:55 is the simplified version of 77:x.

So when Mrs. Jones makes 77 candles, she will make 55 wax warmers.

Answer: C. 55
