Answer:
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)
answer: 9 weeks
2.
50 ÷ 6 ≈ 8.3, then we round up to 9
answer: 9 weeks
