Ventura Coal mined 6 ¨ø tons on Monday, 7 ¨ú tons on Tuesday, and 4 ¨ö tons on Wednesday. If the goal is to mine 25 tons this week, how many more tons must be mined?

25-(6+7+4) =

25 - (6+7+4) =

9

To find out how many more tons must be mined, we need to calculate the total tons of coal mined from Monday to Wednesday and subtract it from the weekly goal of 25 tons.

The total tons of coal mined from Monday to Wednesday can be found by adding the amounts mined each day:
6 ¨ø tons + 7 ¨ú tons + 4 ¨ö tons = 17 tons

To determine how many more tons must be mined, subtract the total tons mined from the weekly goal:
25 tons - 17 tons = 8 tons

Therefore, Ventura Coal must mine 8 more tons to reach the weekly goal of 25 tons.
