Question

In a restaurant Patty's share of the expenses for lunch was $2 more than Karen's. Karen did not have enough money to pay her share, so Patty paid $8 of the expenses and Karen paid the remaining $4. How much did Karen owe Patty to settle the lunch expenses?
1. $1
2. $3
3. $5
4. $6
5. $9

Answer 1

P - K = 2 .....(1)
P + K = (8+4) =12 .......(2)
On solving, P = $7 and K = $5
Since P paid $8 , so K owes $1 to P.
