Answer:
$40
Explanation:
Let the total bill be "x"
Now,
Anna paid 40% (40/100 = 0.4) of the bill, that means
Cassie paid 100 - 40 = 60% of the bill, that is 60/100 = 0.6
Anna paid 0.4x & Cassie paid 0.6x
Cassie's amount is 8 dollar more, so we can write:
0.6x - 8 = 0.4x
Now, we solve for x:
0.6x - 0.4x = 8
0.2x = 8
x = 8/0.2
x = 40
THe total bill is $40
