Suppose that you deposit money into a savings account that receives 5% interest per year on the amount of money that
is in the account for that year.
Assume that you deposit $400 into the account initially.
By what single number could you multiply the $400 by in
order to calculate how much money is in the account at the
end of a year?
Type your answer as a number only, no letters or spaces or
other characters.
Round to the nearest hundredth as appropriate.
