Answer:
36 containers of fish food are left
Step-by-step explanation:
Habib sells 18 containers of fish food. because each box contains 9 containers of fish food. So the number of containers of fish food at Habib's Pet Shop is 54. So 54 - ( 2 × 9 ) = C
54 - 18 = C.
54 - 18 = 36 so C = 36
1.50 I think
51.50-50 equals 1.50
4x+4
7x -3x +4
Combine like terms
7x-3x = 4x
Substitute back into the expression
