Answer:
£90
Step-by-step explanation: In the following ratio, the total of Brian and Collin's ratio is 4 (1+3). If there total is £40, you would set up an equation 4x=40 to find out how much 1 equals in the ratio. After solving this equation, you get x=10. To find the amount of money Alex recieved, you would multiply 9 x 10 and get £90. I hope this was helpful.
