The sales was increased by 44.4%.
Step-by-step explanation:
- Lets do this cumulative
- 90 of 10 % = 9 which is 99
- 90 of 10 % = 9 which is 108
- 90 of 10% = 9 which is 117
- 90 of 10% = 9 which is 126
- 90 of 4 % = 3.6 which is 129.6
- 90 of 0.044% = 0.0396 which is 129.99
- This comes to nearly 44.44 to be closer there was an increase.
- Always rule 1 approximation use 50% of 90 if it is above 130.
- Down it to 40% of 90 see if the sales is lower than 130.
- It should always start with 50,40,30....10 percents.
- Alternative should be 10,1 or decimals.
- Approximation using decimals rounding up becomes simple.
Answer:
Step-by-step explanation:
f(x) = -5x + 8(7 - x)......when f(x) = 160
160 = -5x + 8(7 - x)
160 = -5x + 56 - 8x
160 - 56 = -5x - 8x
104 = - 13x
-104/13 = x
-8 = x <====
Answer:
-8
Step-by-step explanation:
you add 5 to -7 to get -2
7 x -1 is -7
so x = -1
8 x -1 = -8
it's x ≤ 3 :))) I found it out after realizing what you were asking
