Respuesta :
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.
The percentage increase in team sales is 44% and this can be determined by using the unitary method.
Given :
The sales increase from 90 units to 130 units.
The following steps can be used in order to determine the percentage increase in sales:
Step 1 - The unitary method can be used in order to determine the percentage increase in sales.
Step 2 - According to the given data, the team sales are 90 units which are 100%. After increasing the sales becomes 130 units.
Step 3 - So, let the percentage of 130 units be 'x'. So, the value of 'x' is:
[tex]x = \dfrac{130}{90}\times 100[/tex]
[tex]x = 144\%[/tex]
Step 4 - So, the percentage increase in sales is:
[tex]{\rm Percentage \; Increase } = 144 - 100[/tex]
[tex]{\rm Percentage \; Increase } = 44\%[/tex]
The percentage increase in team sales is 44%.
