Apackage of breakfast bars has 17 bars in it. the total mass is 76.5 grams. what is the mass of each bar in grams

Step-by-step explanation:

Let c represent the number of large candles Jane sold. Then 98-c is the number of small candles. Her revenue is ...

  8c +5(98-c) = 625

  3c + 490 = 625 . . . . . . eliminate parentheses, collect terms

  3c = 135 . . . . . . . . . . . . subtract 490

  c = 45 . . . . . . . . . . . . . . divide by 3

Jane sold 45 large candles and 98-45 = 53 small candles.
