<h2>Answer with explanation:</h2>
It is given that:
one pound of swordfish costs as much as 1.5 pounds of salmon.
Let x be the cost of one pound of salmon.
This means that the cost of one pound of swordfish is: 1.5x
Mrs. O pays $39 for 2 pounds of salmon and 3 pounds of swordfish.
This means that:
This means that cost of 1 pound of salmon= $ 6
Hence, cost of 2 pounds of salmon= $ 12 ( since, 6×2=12 )
and cost of 1 pound of swordfish= $ (1.5×6)= $ 9
Hence,
cost of 3 pound of swordfish= $ (9×3)=$ 27
- Hence, ratio of amount of money she pays for salmon to the swordfish is:
12/27= 4/9
i.e. 4:9
- and the ratio of amount of money she pays for swordfish to the salmon is:
9:4
