Answer:
12 weeks
Explanation:
We are told that Angelo deposits the same amount of money each week and in 8 weeks he deposits a total of $ 280; therefore, the amount he deposits in one week is
[tex]\$280\div8=\$35[/tex]
This means, Angelo deposits a fixed $35 per week.
How many weeks until Angelo collects a total of $420 in his bank account?
The answer is found by dividing $420 by the amount he deposits each week ($35)
[tex]\$420\div\frac{\$35}{\text{week}}=12weeks[/tex]
which is our answer!
