On Monday morning, Mr. Descartes asked his Algebra
Il students whether they had gone to the carnival in
town over the weekend. "I did," said Kristen. "I went on
the Teacups ride twice, the rollercoaster twice, and the
Spinning Vortex once. I had a lot of fun for only $20.0"
went on those rides, too!" exclaimed Jorge. "Just once
each on the Teacups and rollercoaster, but three times
on the Spinning Vortex, all for $25.""I did five Teacup
rides," said Lakesha. "And two rollercoaster rides, and
one Spinning Vortex. I spent $29."Marc listed off the
same rides. "Three Teacups for me, plus two
rollercoasters, plus two rides on the Spinning Vortex, all
for -- "You don't need to say," interrupted Mr.
Descartes. "I know how much you spent."How much
are the rides? How much did Marc spend?
Write a system of equations to represent this situation:
