Holly has $462 in her bank account and takes out $15 each week but does not put any back in. Write an equation/expression to represent the amount of money she has in her bank account.

Therefore required expression is

y = 462 - t*15

where y represents the amount of money in her bank account in dollar after t week.

Step-by-step explanation:

Given that,

Holly has $462 in her bank account and takes out $15 each week but does not put any back in.

She takes out $15 on first week.

The remaining amount of her bank account is = $ (462-15)

=$ (462 - 1*15)

If she withdraws $15 on second week.

The remaining amount of her bank account is = $ (462-15-15)

=$ (462 - 2*15)

Similarly after third the amount in her account is = $ (462 - 3*15)

From the above it is cleared that

The amount in her account after t week is

=$ (462 - t*15)

Therefore required expression is

y = 462 - t*15

where y represents the amount of money in her bank account in dollar after t week.
