Answer:
The ratio of the amount for swordfish to the amount of salmon is 6:4
Step-by-step explanation:
Given as :
The price for 1 pound of swordfish = The price of 1.5 pound of salmon
So, On this relation
The price for ( 1 × 2 ) pound of swordfish = The price of ( 1.5× 2 ) pound of salmon
i.e The price for 2 pound of swordfish = The price of 3 pound of salmon
Now According to question
Mrs. O pay the total money for 2 pounds of swordfish and 3 pound of salmon = $ 39
Let the money she pay for swordfish = 2 sw
And The money she pay for salmon = 3 sa
∵, The total money she pay for both = $ 39
I.e 2 sw + 3 sa = 39
As 2 sw = 3 sa
So, 3 sa + 3 sa = 39
Or, 6 sa = 39
or, sa = =
∴ sw = ×
or, sw =
Now, the ratio of the amount for swordfish to the amount of salmon =
I.e The ratio =
Hence The ratio of the amount for swordfish to the amount of salmon is 6:4
Answer
Since the values on both sides are different, hence graph of option C is correct.
<h3>What is inequality?</h3>Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Solutions to inequality graphs
Inequalities are an equation that does not include only the equal sign.
The system of inequalities are;
The first function is an exponential function.
Since the values on both sides are different, hence graph of option C is correct.
