Furniture costs 3% more than last year.
So last year furniture cost 97% of the current price.
Price for tables last years was = 97/100 × $2950 = $2861.5
Which is $2862 to nearest dollar.
Price for chairs last year = 97/100 × $3850 = $3734.5
Which is $3735 to nearest dollar.
Equation for one year:
0.0725(400)
But we have 7 years:
7(0.0725(400))
Multiply in the parentheses
7(29) = 203
400 + 203 = 603
You now have $603, and made $203
