Answer:

Approx. 59% increase.

Step-by-step explanation:

Today - 221

Yesterday - 139

difference (today - yesterday) = 82

How to find percent:

((part)/(whole)) = ((x)/(100))

In this case, the part is the difference, and the whole is the value of an item yesterday, so the equation is:

82/139 = x/100

cross multiply

8200 = 139x

Inverse operations

8200 = 139x

/139       /139

8200/139 = x

approx. 59 = x
