Answer:
Step-by-step explanation:
What I would do is convert everything to have a denominator of 10 so it could be easier to add.
6 would equal 60/10
7 would equal 70/10
2/5 would equal 4/10
now add all together
60/10 + 70/10 + 4/10 +9/10 and you get 143/10. If you wanted to simplify you would get 14 3/10 or 14.30
y=x2-1 is Not Linear
$2.06 tax
$24.99 pants
$27.05 total cost with tax
24.99 + tax = 27.05
tax = 27.05 - 24.99
27.05 - 24.99 = 2.06
