Airida [17]

Given:

At the store a cell phone cost 1.1 times as much as it sells online.

The cost of it is $888.98 online.

To find:

How much more does it cost from the store?

Solution:

Cost of a cell phone online = $888.98

At the store a cell phone cost 1.1 times as much as it sells online. So, cost of the cell phone at store is

1.1\times (888.98)=977.878


The cost of cell phone at store is $977.878 .

The difference between the cost of cell phone at store and online is

\$977.878
-\$888.98=\$88.898

Therefore, the cell phone cost is $88.898 much more at the store.
