Question 50179: If someone goes on a vacation and buys souvenirs for $10, $3 and $.50 and spends exactly $100 and buys at least one of each item...how do I write an equation to show the relationship? Answer by rchill(405) (Show Source):
You can put this solution on YOUR website! The unknowns are the items, even though we know the prices of each. Because there are 3 prices, there must 3 items, or unknowns. Let a represent the number of items that cost $10, b represent the number of items that cost $3, and c represent the number of items that cost $.50. Because these three totals add up to exactly $100, we have the equation .
