Mark is buying candy for his school club. He wants to buy snickers and starbursts. Snickers cost
$3.99 per bag and Starburst cost $2.99 per bag. He cannot exceed $239. He wants to buy at
least twice as many snickers as starburst. Write a system of inequalities to help him solve this
problem of how many bags to buy of each. Let x be the number of bags of starburst and y be the
number of bags of snickers.
