45% of 120 is 0.45*120 = 54.
The monthly cost is 45% higher than it was last year, so it costs $54 more than the $120 it cost last year.
That is, the new monthly cost is 54+120 = $174.

$120 times 12 = $1440 as last year's total.
The monthly bill went up 45%.
Then 120 times 0.45 = 54.
We add 120 to 54 and get $174 as the new monthly bill this year.
If you want to know what the new yearly total will be, just multiply $174 times 12.
Last year you paid $1440 and this year it will be $2088, which is 174 times 12.
