Jerry is paid twice a month. Last month, his first paycheck was for $52. He paid $18 for gasoline and $20 for food. His next paycheck was for $65. He paid $16 for gasoline and $25 for food. What is his balance?

Jerry's current balance is $41.

Step-by-step explanation:

We need to subtract what he spent, and add what he gained.

So:

(Money spent)

$18 + $20 = $38

(Current balance)

$52 - $30 = $22

(Current balance)

$65 + $22 = $87

$25 + $16 = $41

Current balance: $41

the discriminant is 64 + 4*1*12 = 112

this is prime.
