Question

Mario set a goal to run 150 miles this month to prepare for a marathon. So far this month, he has run 75 miles. Write and solve an equation to show how many miles Mario has left to run this month to reach his goal.

m − 75 = 150; m = 225 miles
m + 75 = 150; m = 75 miles
75m = 150; m = 2 miles
m over 75 equals 150; m = 11,250 miles

Answer 1

m + 75 = 150; m = 75 miles

Explanation:

He ran 75 miles.

75

He has another m miles to run. The total miles he will run is m + 75.

m + 75

The total he wants to run is 150 miles, so

m + 75 = 150

Subtract 75 from both sides.

m = 75

Answer:

m + 75 = 150; m = 75 miles
