Image of the I-Web Work Items page. A circle and arrow, labeled '1,' indicate the 'Quantity' box. A second circle and arrow, labeled '2,' indicate the 'Dollars Needed' amount in the 'Tasks' block.

Now I need to change the quantity to reflect how much of the building needs to be painted; in this case, 565 square feet. I click on the "Quantity" box and type "565" (1).

After I press Enter, the application recalculates the Needed dollars by multiplying the three figures again (unit times cost factor times quantity).

The first Needed dollars amount for this task was $2.72, which is the product of this equation: 1.96 X 1.392 X 1.

The revised Needed dollars amount, which takes into account the new quantity, is $1,541.50 (2), which is the product of this equation: 1.96 X 1.392 X 565.
