with out pass
ticket cost is 3x$
with the pass
cost is 15+2.25x$
15+2.25x=3
1500+225x=300x
1500=75x
x=
must be used 20 times or more.
2. After a 17% price reduction, a boat sold for $20,750. what was the boat's price before the reduction> (round to the nearest cent, if necessary)
original price is
x-0.17x=20,750
x(1-0.17)=20,750
x(0.83)=20,750
