Question

A travel agency offers different getaways to New York. Plan A includes hotel accommodations for 3-nights and 2-pairs of baseball tickets for $645. Plan B includes hotel accommodations for 5-nights and 4-pairs of baseball tickets for $1135. How much does a single hotel cost and how much does a single pair of baseball tickets cost?

Answer 1

3n(n stands for nights)+2b(b stands for baseball tickets)=$645
5n+4b=$1135
6n+4b=$1290
n=$1290-$1135
  =$155
b=($645-($155*3))/2
  =$90
