Answer:
12 weeks
Step-by-step explanation:
If John is aiming to save $100, with $6 a week and he has already saved $28. The leftover amount to be saved is $100 - $28 = $72
In one week → $6
2 weeks → $12
3 weeks → $18
and so on..
[tex]\frac{72}{6} = 12[/tex]
John will need 12 more weeks to save a total of $100.
