It would be 340%. First, you need to find out what the fraction is for 2/5. 2/5 as a decimal would be .4. Next you put that back with the three which is 3.4. After that, you need to turn that into a percentage by multiplying it by 100 which then equals 340. add the % to it and that gives you 340%.

Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when x is equal to 0)
<u>1) Determine the slope (m)</u>
where two points that the line passes through are
and 
We're given the point (2,10) and the y-intercept of 4. Recall that the y-intercept occurs when x is equal to 0. This means that the y-intercept occurs at (0,4), giving us our second point.
Plug these points into the equation

Therefore, the slope of the line is 3. Plug this into 

<u>2) Determine the y-intercept (b)</u>
The y-intercept is given; it is 4. Plug this back into 

I hope this helps!
For the $2,000 account at 4%, Reuben earned $80, For the $6,000 account at 9%, he earned $540.
a: $540+$80=$620
b: 12.90322580645161% 8000/620=12.90322580645161
