Answer 1

Keyoka has some bows. She has 8 more purple bows than green bows. She has twice as many orange bows as purple bows. She has 9 green bows. How many bows does Keyoka have altogether?

Student's solution: Work backwards.
Keyoka has 9 green bows.
She has 8 more purple bows than green bows (9 + 8 = 17).
She has twice as many orange bows as purple bows (17 × 2 = 34).
So Keyoka has 9 + 17 + 34 or 60 bows.

Use a similar strategy to solve this problem.

Jessica has some markers. She has 5 more back markers than blue markers. She has 4 times as many red markers as black markers. She has 8 blue markers. How many markers does Jessica have altogether?

Answer 2

Okay, look:

You know she has 8 blue markers. You also know that she has 5 more black markers than blue markers. So 8 + 5 = 13. So now we know she has 13 black markers. She has 4 times as many red markers than black markers: 13 x 4 = 52.

So:

Blue = 8
Black = 13
Red = 52
