Jackson goes to the movies with a friend his ticket cost $8.25.he buys some popcorn with ($2.75) & a soda with ($2.50). if he started the day with $15, how much money does he have left over?

i used to know how to do this in 7th but i forget easily

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!
