Question

3. Elena walked 12 miles. Then she walked 0.25 that distance. How far did she walk all together? Select all that apply.

A. 12 + 0.25 ⋅ 12
B. 12(1 + 0.25)
C. 12 ⋅ 1.25
D. 12 ⋅ 0.25
E. 12 + 0.25

Answer 1

B. 12 + 0.25 ⋅ 12

C. 12(1 + 0.25)

Explanation:

It asks you how far she walks all together, so you need to find that answer first to figure out the rest correctly. Now, the total she walked is 15 miles. B. and C. give you 15, however, the rest give you different answer than the total she actually walked.

Answer 2

A, B, C

Explanation:

12+0.25*12=12(1+0.25)=12*1.25
