Compare how many place values the 3's have.
The 3 in 302754 is in the 6th place value, while the 3 in 53891 is in the 4th place value. Each place value is 10 times the one below it. Since the first 3 is 2 place values ahead, 10*10=100 times.
860 *11/100=9460/100=94.6
94.6 is earned
$4.07 × 9.6= $39.072 or $39.07; $20 × 2= $40; 40 - 39.07= 0.93.
The answer is $0.93.
Hope this helps :)
