The following expression shows the amount of money in the account after x weeks.

If $20.50 was added to the account for 10 weeks we can substitue 10 as the x:

$370.85 will be in the account after 10 weeks

$370.85

Step-by-step explanation:

given:

amount of money after x weeks

= 165.85 + 20.5x

after 10 weeks, x = 10 (substitute into equation)

amount of money after 10 weeks

= 165.85 + 20.5(10)

= 165.85 + 205

= $370.85

First multiply 10 by 20.5 because x represents the number of weeks.  You get 205.  Next add 165.85 to that and you get 370.85 as your final answer.
