There were 397 cell phones sold at an electronic store in January. Since
then, cell phone sales at the store
have increased at a rate of 3.25% per
month. At this rate of growth, which
function can be used to determine the
monthly cell phone sales m months
after January?
F p(m) = 397 (0.0325)
Gp(m) = 397 (1.0325)
H p(m) = 397 (1.0325)m+1
J p(m) = 397 (0.0325)+1

Nine more than four times a number is the same as one less than twice the number. find the number?
