Which strategy would not correctly solve this story problem?

There are 14 bikes for sale at a bicycle store. Four of the bikes are black, 5 are white, and the rest are red. How many bikes are red?


A.

Translate into an equation. 4 + 5 + r = 14






B.
Use logical reasoning. There were 14 bikes to start with. Subtract the number of black bikes (4) and subtract the number of white bikes (5). The remaining bikes must be red.





C.
Work backward. Start with 14 bikes and add 4. Then subtract 5. The number left is the number of red bikes.





D.
Draw a diagram. Draw 14 circles. Cross out 4 of the circles and then cross out 5 more circles. Color the remaining circles red

Which strategy would not correctly solve this story problem?

Tanya had a dog-walking service during the summer. She took 4 dog walks on Tuesdays and 2 dog walks on Thursdays. How many dog walks did Tanya take after 9 weeks of her dog-walking service?





A.

Make a table.



Week 1 2 3 4 5 6 7 8 9
Total Walks 6 12 18 24 30 36 42








B.

Translate into an equation. 9 × (4 + 2) = d






C.

Draw a diagram. Draw 9 circles. Add 4 + 2 to get the number of dog walks each week (6). Write 6 in each circle. Add the numbers in the circles.






D.

Use logical reasoning. In 1 week Tanya took 4 dog walks on one day and 2 dog walks on another for a total of 6 walks each week. So to figure out the total number of walks, add the number of weeks (9) to the number of walks each week.
