Answer:
$120.
Step-by-step explanation:
The amount he sells the tool kit for = 80 + 20% of 80

m - 0.20m = 96
0.8m = 96
m = $120.
Answer:
K = 6
Step-by-step explanation:
Plug in what the letter equals to
Equation will look like:
2(11) = 4 + 3k or 3k + 4 = 2(11)
multiple the 2 by 11 and get 22
3k + 4 = 22 subtract the 4 so it can leave the 3k alone
22 - 4 = 18 now divide 3 from k and do it in the other side
18/3 = 6
so K = 6
