Answer:

Jinfa's paycheck = 318

Explanation:

  • We can let x represent Jinfa's paycheck in dollars.
  • Since Jinfa spent two-thirds of his paycheck on car repairs, he spent 2/3x dollars.
  • Since he then bought a $40 gift for his mom, he spent 2/3x + 40 dollars in all.

Since Jinfa had $66 left, we can use the following equation to find out how much his paycheck was in dollars:

2/3x + 40 + 66 = x

(2/3x + 106 = x) - 2/3x

(106 = 1/3x) / (1/3)

(106 = 1/3x) * 3

318 = x

Thus, Jinfa's paycheck was 318 dollars.
