Answer:
29
Step-by-step explanation:

Answer is 5/2 i took that quiz too
First calculate how many cookies makes in one hour and then I calculate the number of cookies he makes in nine hours
The answer should be 37
2(x+8) = 3(x-7)
distribute
2x+16 = 3x-21
Subtract 2x from both sides
2x+16-2x = 3x-21-2x
16 = x-21
Add 21 to both sides
16+21 = x-21+21
Round 198 to 200, then do a mental sum for 6x200 (1200) then subtract 6x2(12) which gives you your answer: 1188
