30. Given problem : You deposited 2 000 dollars, then you will earn 6% simple interest.
Question: How long will it become 2 600 dollars.
Well, you didn’t mention if it’s an annual interest or monthly interest.
But let’s say that it’s a monthly interest, then let’s start solving:
=> 2000 Is the original amount + 6% interest
first month = 2000 * .06 = 120
=> 2000 + 120 = 2120
2nd month = 2120 *.06 = 127.2
=> 2120 + 127.2 = 2247.2
3rd month = 2247.2 *.06 = 134.832
=> 2247.2 + 134.832 = 2382.032
4th month = 2382.032 * .06 = 142.92192
=> 2382.032 + 142.92192 = 2524.95392
5th month = 2524.95392 * .06 = 151.497
=> 2524.95392 + 151.497 = 2676.45
Thus, on the fifth month she will earn this amount.
0.2 is the answer I believe ^^
Answer:
Yes, after 10 key presses, both will arrive at the number 30.
Step-by-step explanation:
The difference between the numbers on the calculators is reduced by 10 with each key press. After 10 key presses, the initial difference of 100 will be zero. After 10 key presses of (-7), the calculator starting at 100 will be ...
100 +10(-7) = 30
After 10 key presses of (+3), the calculator starting at 0 will be ...
0 +10(+3) = 30
Both calculators will show 30 after 10 key presses.
I’m not for sure of the answer but i do know that the two subtractions in the middle would turn into a + and i think you add the -5/8 + 3/10
