Terri walked 3.825 miles yesterday. Today she walked 5.5 miles. How many more miles did terri walk today than yesterday?

Brenda chose B as the correct answer. How did she get that answer?

She got the answer by doing 5.5-3.825

The equation would be

5.5 - 3.825 =

and if you subtract, the answer is 1.675 miles.

this is the correct answer because the number of miles Terri walked yesterday needs to be subtracted from the number of miles Terri walked today.

so

5.5 - 3.825 = 1.675
