10/60= 1/6
p(event)= # of ways an event can occur/sample space zice(the number of possible outcomes)
If it is 40% off, it means you have to pay 60% of its price.
$67 × 60/100 = $40.20
the 8% of sales tax is added from the $40.20
$40.20 × 8/100 = $3.22
total price = $40.20 + $3.22 = $43.42
I think the slope =21 m
i am not confirm if its not correct
