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