## Algebra 1

$3*2=6$ $2*3=6$ Jeff finished 3 tables in 6 minutes, and Tiffany finished 2 tables in 6 minutes. Combined, they finished 5 tables in 6 minutes. Thus, they can finish 45 tables in 54 minutes. Stacie finishes one table in 3 minutes. Thus, Stacie finished 18 tables in 54 minutes. Nick finishes one table in 3.5 minutes. Thus, Nick finished 15.4 tables in 54 minutes. 33.4 total tables are done. $(x/3+x/4+x/5+x/3.5) = 11.6$ $210*(x/3+x/4+x/5+x/3.5) = 11.6*210$ $70x+52.5x+42x+60x = 2436$ $224.5x=2436$ $x=2436/224.5$ $x=10.85$ $10.85+54 = 64.85$
