Can somebody please help me set up this problem

A home valued at $150,000 is assessed $2700 in real estate taxes. At the same rate, how much are the taxes on a home valued at $175,000?

x = tax rate

150,000x = 2700
x = 2700/150,000

175,000x = y
175,000*(2700/150,000) = y

y = $3,150 in taxes

At a value $150,000, tax is $2700
If value is $1, tax is $2700 / $150,000 (Divide both value above by $150000)
If value is $175,000, tax is ($2700 / $150,000) * $175,000 = $3150. (Multiply tax for $1 with actual new value)
