Which strategy would not correctly solve this story problem?

Ella babysits her baby brother for 30 minutes on Monday, for 45 minutes on Thursday, and for 35 minutes on Friday. Ella will continue this schedule for 6 weeks. How many minutes will Ella babysit in 6 weeks?

A.

Translate into an equation. (30 + 45 + 35) : 6 = m

B.

Use logical reasoning. Add together the number of minutes Ella babysits each week: 30 + 45 + 35 = 110. Multiply 110 by the number of weeks Ella continues this babysitting schedule.

C.

Draw a diagram. Draw 6 large squares. Add up the numbers 30, 45, and 35 to get 110. Write 110 in each square. Add up the numbers in the squares.

D.

Make a table.

Mateo Clark · Answer 1

The strategy or equation which do not solve this problem is letter A and B.

The letter A goes m = (30+45+35) / 6, the question asked how many minutes Ella will babysit in six weeks. In a week Ella babysits for 110 minutes, instead of dividing it by 6 weeks (which is shown in the equation of letter A), you have to multiply by 6 weeks. It should go like this, m = (30+45+35) x 6.
