Answer:
$370.85
Step-by-step explanation:
The following expression shows the amount of money in the account after x weeks.
[tex]165.85+20.5\cdot{x}[/tex]
If $20.50 was added to the account for 10 weeks we can substitue 10 as the x:
[tex]165.85+20.5\cdot{10}=165.85+205=370.85[/tex]
$370.85 will be in the account after 10 weeks
