The seventh grade class supplied bags of snacks and beverages for the school dance They supplied19 more beverages than bags of snacks The dance was supplied with a total of 371 items.

The number of number of bags of snacks = m = 176

The number of beverages supplied = m + 19 = 176 + 9 = 185

Step-by-step explanation:

Let us assume the number of bags of snacks = m

So, the number of beverages supplied = m + 19

Total number of items supplied = 371

⇒ Number of (snacks + beverages) supplied = 371

⇒ m + (m + 19) = 371

or, 2 m = 371 - 19 = 352

or, m = 352 / 2 = 176

⇒ m = 176

Hence the number of number of bags of snacks = m = 176

So, the number of beverages supplied = m + 19 = 176 + 9 = 185
