Answer:

The percentage increase in the amount in her savings is 17.9%

Step-by-step explanation:

The formula for percentage increase is given as,  

Percentage\:Increase=\dfrac{New\:Value-Old\:Value}{Old\:Value}

In previous month, amount of saving in Sally’s account was $200.  

In the current month she added $35 and earned an interest of $0.75. So the total earning in current month will be,  

Total earning = Amount in previous month + Amount added + Interest earned  

Total earning = $ 200 + $ 35 + $ 0.75  

Total earning = $235.75

So, current month amount of saving in account is $ 235.75 which becomes new value and previous month balance that is $ 200 becomes old amount.  

Therefore, New value = $ 235.75 and Old value = $ 200  

Substituting the values in the formula,  

Percentage\:Increase=\dfrac{235.75-200}{200}

Percentage\:Increase=\dfrac{35.75}{200}

Percentage\:Increase=0.17875

Percentage\:Increase=17.875

Rounding to nearest tenth means one digit after the decimal place. So, percentage increase is 17.9 %

Which point of intersection is the solution to the system that of equations y= 2/5x-1/2 and y=-1/3x+2/3
Mrrafil [7]

Answer:

x = 35/22

y = 3/22

Step-by-step explanation:

y= 2/5x-1/2 ................(1)

y=-1/3x+2/3 ...............(2)

10*(1)

10y = 4x -5 ...................(1A)

3*(2)

3y = -x +2  ....................(2A)

To find intersection, solve for y & x

4(2A) + (1A)

12y+10y = -4x+4x +8-5

22y = 3

y = 3/22

Substitute in (1)

3/22 = 2/5x -1/2

multiply by 110

15 = 44x - 55

70 = 44x

x = 70/44 = 35/22
