Answer:
Micah: 16 x (18 + 6)
Trudy: 16 x 18
Explanation:
Trudy orders 18 pizza pies, and each have 16 slices right? So 18 x 16 = 288. so then Micah orders 6 more which means 18+6= 24 x 16. (Remember the 16?)
This is the equation:
16 x (18 + 6)
16 x 24
-------------------------------------
Trudy: 16 x 18
Micah: 16 x (18 + 6)
