A)x=$1,600-0.05($1,600)

C)x=0.05($1,600)+$1,600
D)x+$1,600=0.05($1,600)

Answer 1

There are two ways you can solve this. You can do:

1600 · 0.05 = 80

Then you add this to your current rent

1600 + 80 = 1680

$1680 will be your rent next month

Another way to do it is:

1600 · 1.05 = 1680

The "1" in 1.05 keeps the 1600, and the .05 adds the additional rent for next month.

The answer is C

x = 0.05(1600) + 1600

x = 80 + 1600

x = 1680
