Well I'll explain in detail but let me tell u the short cut.
Since 1.5 sec= 1500 millisecond and it will be multiplies by 0.023$=34.5$
this is quick calculation so u can easily eliminate answers A,B.C and adding 4.35 and 1.07 will be 5.42 so D can be eliminated too. Then Answer is E.
And for detailed 34.5+5.42=39.92.
Hope its clear?

Since 1.5 seconds = 1.5 x 1000 = 1500 milliseconds, the total cost is:

1.07 + 0.023(1500) + 4.35 = $39.92

Answer: E
