Let x represent the number of pounds of Swiss cheese that Marsha bought.

We were told that Marsha buys 3 pounds of cheddar cheese and some Swiss cheese Both cheeses cost $450 per pound. This means that the cost of 3 pounds of cheddar cheese is 3 * 4.50 = 13.5

Also, the cost of x pounds of Swiss cheese is 4.5 * x = 4.5x

If the total cost is $24.75, it means that

4.5x + 13.5 = 24.75

The equation is

4.5x + 13.5 = 24.75

We would solve for x. Thus,

4.5x = 24.75 - 13.5

4.5x = 11.25

x = 11.25/4.5

x = 2.5

Thus, she bought 2.5 pounds of Swiss cheese
