Answer: 33.33%. $100. 26.67%.
Step-by-step explanation:
To find what percentage he has of the cost, we can divide what he has by the total amount and multiply by 100.
(50/150)*100 ≈ 33.33%
To find how much more he needs, we will use subtraction.
What he needs - What he has = $140 - $40 = $100
We will use the same steps as before. To find what percentage he would have of the cost if he had $40, we can divide what he has by the total amount and multiply by 100.
(40/150)*100 ≈ 26.67%
