a) Define the variable(s)
b) Write a system of equations for the situation.

Answer 1

a) let 's' = number of bags of snacks

b) let 's+50' = number of bags of beverages

s + s+50 = 400

Explanation:

a) let 's' = number of bags of snacks

b) let 's+50' = number of bags of beverages

s + s+50 = 400

solve:

2s + 50 = 400

2s = 350

snacks = 175

beverages = 175+50 or 225

total = 400
