Answer:
only cheddar: 10 lbs
only swiss: 6 lbs
mixture: many possible amounts
equation: 3x+5y=30
Step-by-step explanation:
If she buys only Cheddar, and she spends all $30, she can buy
10 pounds.
If she buys only Swiss, and she spends all $30, she can buy
6 pounds.
If she buys a mixture of both cheeses, there are many possible amounts that she could buy.
The equation that models the amounts is 3x + 5y = 30, where x is the pounds of Cheddar and y is pounds of Swiss.
