Kyle earned 4 times as much as Ken last summer. If they earned a total of $750, how much did they each earn? Show all work

(Please help will give brainliest)

600, 150

Step-by-step explanation:

Kyle is x

ken is y

x = 4y

x+y = 750

replace x with 4y

4y + y = 750

5y = 750

y = 150

so ken earned 150

x + 150 = 750

x = 600

so Kyle earned 600

problem:

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

f(5/2) = 10/3

i hope this !
