Answer:
$375 dollars.
Step-by-step explanation:
Jinfa received a paycheck. He spent two-thirds of his paycheck on car repairs. This means he used 2 parts out of 3 parts of his paycheck for car repairs.
After the car repairs, Jinfa bought a $40 gift for his mother. So we subtract 40 to the remaining amount.
After all these expenses, Jinfa had $85 left. This remaining amount represents 1 part of his paycheck.
To find the total amount of Jinfa's paycheck, we need to determine the value of 3 parts (representing the whole paycheck). We can do this by dividing the remaining amount ($85) by 1 part and then multiplying by 3.
So, Jinfa's paycheck is approximately $375.
