Answer:
$92
Step-by-step explanation:
Dominik's monthly income is $1,860 and he wants that his credit card payments and student loan keep him within a limit of 20%. So,
$1,860*20%= $372
According to this, his credit card payments and student loan can't be more than $372. Considering that his student loan is $280 per month:
$372-$280=$92
The largest monthly payment dominik can afford for the television set, to maintain his credit card payments and student loan within a 20% limit is $92.
