A. All simple machines are useful in some way, weather that be making it easier to lift heavy objects, activating other machines, or something else.

Answer:
B 16 Bowls
Step-by-step explanation:
Turn 3 3/4 into a decimal
3.75 times 16 is 60
Remark
The trick to this question is realizing what you took 1/3 of. Did you take it of the 150000 or is it 1/3 of some total you have to find. I don't think you could come up with a third choice.
It turns out that the answer is 1/3 of a number you don't know.
Equation
(1/3) x = 150000 Multiply both sides by 3
3*(1/3) x = 150000 * 3
x = 150000 * 3
x = 450000
Conclusion
The amount the company makes is 450000 dollars / year.
