Answer:
Russel: £80
Sarah: £200
Terry: £320
Step-by-step explanation:
You can rewrite the ratio of 2:5:8 as 2x, 5x, and 8x
Now, it is stated that if Sarah gets an extra £120 she will have the same as Terry
Terry's money is written as 8x as mentioned previously, and Sarah's money is now 5x+120. We know that these two things are equal so you can write the following equation:
5x+120= 8x
Now subtract 5x from both sides to get:
120=3x
Divide 3 from x and 120 to get:
x=40
Now you can simply plug in 40 for each of the ratios (2x, 5x, and 8x)
Russel: £80
Sarah: £200
Terry: £320
