Each term is 0.19 more than its predecessor. You have

0.35=0.16+0.19

0.54 = 0.35+0.19

So, we can assume that the next terms will be

0.73 = 0.54 + 0.19

0.92 = 0.73 + 0.19

Kryger [21]

There is a 47% decrease in Jane's closet space.

Step-by-step explanation:

Old measurement of closet = 66 square feet

New measurement of closet = 34.98 square feet

Change = New value - Old value

Change = 34.98 - 66 = -31.02 square feet

The negative sign indicates the decrease.

Decrease percent = \frac{Change}{Old\ value}*100

Decrease\ percent=\frac{31.02}{66}*100 = \frac{3102}{66}\\Decrease\ percent=47\%

There is a 47% decrease in Jane's closet space.
