Tacy has some roses. She has 5 more pink roses than red roses. She has twice as many yellow roses as pink roses. She has 8 red roses. How many roses does Stacy have altogether? Student's solution: Work backwards Stacy has 8 red roses. She has 5 more pink roses than red roses (8 + 5 = 13). She has twice as many yellow roses as pink roses (13 * 2 = 26). So Stacy has 8 + 13 + 26 or 47 roses. Use a similar strategy to solve this problem. Donna has some notebooks. She has 4 more blue notebooks than green notebooks. She has 3 times as many black notebooks as blue notebooks. She has 6 green notebooks. How many notebooks does Donna have altogether?

Randall Davis · Answer 1

You would have to start by adding the green notebooks and the blue notebooks

6+4=10

Then you can multiply the blue and black notebooks

3*4=12

Then you can solve

6+10+12=28

So Donna has 28 notebooks altogether
