Answer:
$85
Step-by-step explanation:
100%-20%=80% and 80% = 0.8
So,
0.8x=68
x=85
we can always find the slope of any line by simply using two points on the line, say let's use (3,4) and (-1,2)

The answer is; 24/75 of the entire cake remained
If 2/5 of the initial cake was eaten, the 3/5 is what remained
MInu ate 1/3 of the 3/5 = 3/15
3/5 – 3/15 = 6/15 remained
Her brother ate; 1/5 of 6/15 = 6/75
6/15 – 6/75 = 24/75 remained
