I was wondering if you have a matrix (AB)t
does matrix A and B both become transposed?
like A^t and B^t?
thank you

An amount of money invested for 1 year in a savings account will earn $1,500. That same amount of money invested in a mini-mall development will earn $4,500 interest in a year, because the interest paid is 10% more than that paid by the savings account. Find the rate of interest paid by each investment.
(AB)t = (Bt)(At)
