Melissa buys 2.5 pounds of salmon and 1.25 pounds of swordfish. she pays a total of $31.25. the swordfish costs $0.20 per pound less than the salmon. what would be the combined cost of 1 pound of salmon and 1 pound of swordfish?

The combined cost of 1 pound of salmon and 1 pound of swordfish is $16.60

Step-by-step explanation:

Let $x be the cost of 1 pound of salmon.

The swordfish costs $0.20 per pound less than the salmon, then $(x-0.20) is the cost of 1 pound of swordfish.

Melissa buys 2.5 pounds of salmon and pays $2.5x for salmon.

Melissa buys 1.25 pounds of swordfish and pays $1.25(x-0.20) for swordfish.

She pays a total of $31.25, then

Solve this equation.

Costs:

1 pound of salmon - $8.40

1 pound of swordfish - $8.20

Combined - $16.60
