8x/8 = 36/8

x = 4.50

Answer 2

Answer:

$4.50

Step-by-step explanation:

first you have to find out how much one avocado costs. to do that, divide 4 by 8 which is 0.5, this means 1 avocado is 0.5. then simple multiplication 0.5 X 9 is $4.50. you can even double check, 8 times 0.5 is $4.

Btw you are not dumb you just gotta try :)
