Let's call the total amount Vita saved last year "T." According to the information given:
$72 = (2/9) * T
To find the total amount Vita saved last year (T), you can isolate T by multiplying both sides of the equation by (9/2) to undo the fraction:
T = (9/2) * $72
T = (9/2) * $72
T = $36 * 9
T = $324
So, the total amount Vita saved last year was $324.
