Peter won £45 as a price. he gave 4/5 of the money to roger and bethan. rogers and bethan shared the money in the ration 2: 3. work out how much they each got

check the picture below.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
