195 rounded to the nearest hundred is 200x5=1000
1. 50% of 60mins is 30mins
2. 10% of 60 mins is 6mins
3.75% of 60 mins is 45mins
Answer:
sale price : $31.72
Step-by-step explanation:
regular price is 100%
sale price, 100% - 35% = 65%
100% ---> $48.80
1% ----> $48.80 / 100 = $0.488
65% --->$0.488 * 65 = $31.72
OR,
we know sale price = total price - discount price = 100% - 35% = 65%
so 65% * $48.80 = $31.72
Answer:
For Joy:
Strategy: Multiply through by 4
For Paulo:
Strategy: Evaluate the bracket
Explanation:
Given
![\frac{1}{4}(12x - 8)=10](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%2812x%20-%208%29%3D10)
Required:
Determine the strategies
For Joy:
Strategy: Multiply through by 4
![4 * \frac{1}{4}(12x - 8)=10 * 4](https://tex.z-dn.net/?f=4%20%2A%20%5Cfrac%7B1%7D%7B4%7D%2812x%20-%208%29%3D10%20%2A%204)
![12x - 8 = 40](https://tex.z-dn.net/?f=12x%20-%208%20%3D%2040)
<em>Done</em>
For Paulo:
Strategy: Evaluate the bracket
![\frac{1}{4}*12x - \frac{1}{4}*8=10](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%2A12x%20-%20%5Cfrac%7B1%7D%7B4%7D%2A8%3D10)
![3x - 2 = 10](https://tex.z-dn.net/?f=3x%20-%202%20%3D%2010)
