Lily starts a savings account with $50. Each month, m, she withdraws $10 from her account. Write an expression that can be used to determine how much money Lily has left in her savings account after a certain number of months.

50 - 10m or 10(5 - m)

Step-by-step explanation:

Since Lily starts a savings account with $50 and each month, m, she withdraws $10 from her account, the expression that can be used to determine the amount left in her savings account after a certain number of months will be:

= 50 - 10(m)

= 50 - 10m

For example, the amount that'll be left in her account after two months will be:

= 50 - 10m

= 50 - 10(2)

= 50 - 20

= 30

She'll have $30 in her account after two months.

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
