Question

Kello has $17 savings.she receives a $11 weekly allowance.write and solve an inequality to find the least amount of weeks it will take her to save $72

Answer 1

Let, the number of weeks = x
It would be: 17 + 11x ≥ 72
Subtract 17 from both sides, 
11x ≥ 55
Divide by 11, 
x ≥ 5

So, at-least he needs 5 weeks for that

Hope this helps!
