Answer:
#540
Step-by-step explanation:
Alan saved $180 in each month
and we have 12 months in a year so we say
$180=12
x=36
here we cross multiply then we have 180 * 36 which is equal to $6480 after that we divide it by 12 and that's $540
Note: I got 36 months because 12 months in a year so multiply by three years that's 36 months
