Jessie saves $6 each week. In how many weeks will she have saved at least $50?

9 weeks

Step-by-step explanation:

Jessie needs to save at least $50, and in order to do that we need to find the smallest number that, when multiplied by 6, will be larger than or equal to $50.

You could 1. multiply 6 until you reach a number greater than or equal to $50, or you could 2. divide $50 by $6 and round up.

1.

6 x 9 = 54 (anything less would not fit the requirements)

9 weeks

2.

50 ÷ 6 ≈ 8.3,  then we round up to 9

9 weeks
