Modeling using Variation

Question

The tax on a property with an assessed value of $65,000 is $500. Using a proportion, find the tax on a property with an assessed value of $80,000

Answer 1

t/80,000= 500/65000

t/80 = 500/65

t/16 = 500/13

t = 16(500)/13

t = 8000/13

t = about $615 tax on $80,000

if $500 tax on $65,000
