The answer is (C) because you multiply each point by 1.5.
The least common multiple of 3 and 8 is 24.
The least common multiple of two numbers is the lowest value number that is a multiple of both the numbers. To find the least common multiple of 3 and 8, you first list their multiples:
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24...
Multiples of 8: 8, 16, 24, 32, 40, 48, 56...
When you compare the two lists of multiples, you can see that the number 24 is the lowest number that is a multiple of both 3 and 8, so it is their LCM, or least common multiple.

Let's Isolate the variable y in each of the cases and then compare with Fiona's equation to determine the solution of the problem
case A) 
Multiply by
both sides


Divide by
both sides

therefore
the case A) is not equal to Fiona's equation
case B) 
Multiply by
both sides


Divide by
both sides

therefore
the case B) is not equal to Fiona's equation
case C) 
Multiply by
both sides


Divide by
both sides

therefore
the case C) is not equal to Fiona's equation
case D) 
Multiply by
both sides


Divide by
both sides

therefore
the case D) is equal to Fiona's equation
<u>the answer is</u>
