First, the initial, pre-inflation, cost of the project was 450 + 30 + 80 = $<<450+30+80=560>>560.

Then, the price of the lumber increased to 450*1.20 = $<<450*1.20=540>>540.

Similarly, the price of the nails increased to 30*1.10 = $<<30*1.10=33>>33.

And the price of the fabric increased to 80*1.05 = $<<80*1.05=84>>84.

Therefore, the new, post-inflation, cost of the project is 540 + 33 + 84 = $<<540+33+84=657>>657.

Thus, the cost has increased by 657 - 560 = $<<657-560=97>>97.

A father is building a playset for his son and needs to purchase lumber, nails, and fabric.  When he started planning the project, the necessary lumber cost $450, the nails cost $30, and the fabric cost $80.  However, recent economic inflation has caused the price of lumber to increase by 20%, the price of nails to increase by 10%, and the price of fabric to increase by 5%.  In dollars, how much more money will it cost to complete the project now (after inflation) than it would have when the father began planning?
