$44.70

#30($1.49)# or #30*1.49#
This type of multiplication is most commonly done in the following format.

#30.00#
x#1.49#

To avoid confusion, the decimal points can be moved two spaces to the right in each number as long as they are returned at the end.

#3000.#
x#149.#

Break each number into parts and multiply those.

#3000# | ..#000# | ... #00# | .......#0#
x#100# | x#100# | x#100# | x#100#

#3000# | ....#0#
..x#40# | x#40#

#3000# | ..#0#
.....x#9# | x#9#

Now multiply each.

#9*0=0# and #9*3000=27,000#
#40*0=0# and #40*3000=120,000#
#100*0=0# and #100*3000=300,000#

The products should then be added to make one sum.

#27,000+120,000=147,000#
#147,000+300,000=447,000#

The total number of decimal places that we removed was four.
So we move the decimal to the left four places to finish.
#447,000. -> 44.7000#

Finally, this number represents an amount of money, so it must be written that way.
