Question

Althea's Plans for Saving $384 Plan Amount to Save Number of Each Week Weeks Needed $20 $30 $50 20 Using Plan B, how many weeks will it take Althea to reach her savings goal? Write an equation to model your work

Answer 1

13 weeks

Explanation:

In the picture attached, data of the problem is shown in a table.

Althea wants to save $384, in plan B she saves $30 each week. The amount of weeks needed is obtained dividing the total amount to save by the amount saved per week, that is:

equation: $384÷$30 = 12.8 weeks

Here, weeks are considered integers, so you have to round this value to the next integer, that is, 13 weeks. To better understand this, suppose you take 12 weeks saving $30 per week, after 12 weeks you will save: $30*12 = $360, which is not enough; with 13 weeks you will save: $30*13 = $390.
