Answer:
Betty got $180
Step-by-step explanation:
If its 2:3 and 2 is 120, that means 120/2 equals 60. 60*3=180
Rewrite it as y=6x-7/5
Flip the x and y
x=6y-7/5
Solve
5x=6y-7
5x+7=6y
5/6x+7/6=y
f^-1(x)=5/6x+7/6
Answer:
The sale is 5% off.
Step-by-step explanation:
- $25 regular price.
- $18.75 sale price.
You need to find the percentage that deducts $1.25 from the regular price. I start with 5% and work my way up from there until I find the answer.
So, <em>5</em><em>%</em><em> </em><em>of </em><em>2</em><em>5</em><em> </em><em>=</em><em> </em><em>?</em>
5% * 25 = 1.25
You needed $1.25, 5% gives you that.
Therefore, the answer is 5%.
