Question 208508
2.	Jane went to the race course with $70 in her pocket.  She bet all $70.  In the first four races Jane won $16, lost$12, lost $7, won $5.  Overall how much money did Jane win or lose?


If I understand this clearly, she bet the entire $70 on each race. After betting the entire $70, she won $16, lost $12, lost $7, and then won $5 after the first 4 races. Therefore, after the 4th race, she is ahead by $2, calculated as: 


($70 + 16 - 12 - 7 + 5) = 72. Therefore, she won ${{{highlight_green(2)}}} ($72 - $70)
