Question

If you opened two Wonka Bars out of 1000, what percent did you open? How many bars out of 1000 would you need to open in order to reach 40%?

A. 0.2%, 800 bars
B. 0.2%, 400 bars
C. 0.4%, 800 bars
D. 0.4%, 400 bars

Answer 1

You opened 0.2% of the Wonka Bars and would need to open 200 bars out of 1000 to reach 40%.

Step-by-step explanation:

To find the percentage of Wonka Bars you opened out of 1000, you divide the number of bars opened (2) by the total number of bars (1000) and then multiply by 100. So, you opened 0.2% of the bars. To determine how many bars out of 1000 you would need to open to reach 40%, you set up the proportion: 0.2/1000 = 40/x. Cross multiplying, you get 0.2x = 40, and then you divide both sides by 0.2 to solve for x. So, you would need to open 200 bars out of 1000 to reach 40%.
