Answer: option c
Step-by-step explanation:
Based on the information given, you can write the following expression:
Where k is the the constant of variation
If y=7/4 when x=1, then you can substitute these values into the expression and solve for k:
Substitute k into the expression. Then the equation is:
Substitute x=3 into the equation. Then, y is:
Since there are 32 fluid ounces in 1 quart and we need 3 quarts we multiply 32 and 3 and get the result of which is 96 we need to divide that by eight to get the correct number to multiply 4.50 by so we get the result of 12 now it is 12 times 4.50 which is 54 so it costs 54 dollars. I hope this was helpful.
