Plz all 4 for, one answer. which one is it?

the first one is correct.

Step-by-step explanation:

because when he picks the first quarter he puts it back. the amount is still the same, so when he chooses his second the numbers won't change

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 !
