Aaron has four times as many cows as does Matthews. Together, they have 30 more cows than Marovich. If Matthews has 60 cows, how many cows do the three have altogether?
If Matthews has 60 cows, Aaron has 4*60 = 240 cows.
Together, Aaron and Matthews have 240+60 = <<240+60=300>>300 cows.
Since Marovich has 30 fewer cows than the combined number of cows that Aaron and Matthews have, Marovich has 300-30 = <<300-30=270>>270 cows.
Altogether, the three have 270+300 = <<270+300=570>>570 cows
