165.85 + 20.5x
 
How much money will be in the account after 10 weeks?

Answer 1

first add your total then times that by 10

Answer 2

$370.85

Explanation:

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

`165.85+20.5\cdot{x}`

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

`165.85+20.5\cdot{10}=165.85+205=370.85`

$370.85 will be in the account after 10 weeks
