Answer:
$1800
Explanation:
Step one:
given data
we are told that Rafael's mortgage payment on his home went up by $117 last month.
let the mortgage payment be x
and $117 is 6.5% of x
6.5/100*x=117
=0.065x=117
Required is the mortgage payment, x
Step two:
divide both sides by 0.065
x=117/0.065
x=$1800
Hence Rafael's mortgage payment before the increase was $1800
