Step-by-step explanation:
Answer:
19 days
Step-by-step explanation:
The first day he saves 2.25.
The second day he has saved 2.25 + 2.25 or 2.25(2).
The third day he has saved 2.25 + 2.25 + 2.25 or 2.25(3)
This continues for x number of days so 2.25x.
If the video game costs 41.95 then set equal to 2.25x and solve.
2.25x = 41.95
x = 18.64
This rounds to 19.
Answer:
1.) 18 is decreasing by 83%
2.) 16 is decreasing by 12.5%
Step-by-step explanation:
Part ÷ Whole = Percent (decimal form)
1.) First, you subtract the smaller number from the larger number: 18 - 3 = 15. Then you find the percent of the part: 15 ÷ 18 = 0.833333333333. This can be rounded to 0.83. Multiply 0.83 by 100 to get the percentage: 0.83 • 100 = 83%. To check your answer, multiply 0.83 by 18. It checks out. 18 is being <em>decreased</em> by 83%.
2.) Subtract 14 from 16 to get 2. Then divide 2 by 16: 2 ÷ 16 = 0.125. Multiply that by 100: 0.125 • 100 = 12.5%. To check this, we multiply 0.125 • 16 = 2. It works. So, 16 is being <em>decreased</em> by 2%.
