At a concession stand, three hot dogs and two hamburgers cost $7.75; two hot dogs and three hamburgers cost $8.50. find the cost of one hot dog and the cost of one hamburger

depends on how many days you are talking about

step-by-step explanation:

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!
