Answer:
$78, $79.20
Step-by-step explanation:
PART A: $60 times 1.3 = $78
you add 30% to 100% to get 130% since it is a mark up, and then you convert to a decimal by going to the left twice then multiplying by original price.
PART B
Since it is a discount you subtract 15 percent from 100, but then add back 5 percent since there is tax applied to get 90%, convert to decimal and multiply by original price to get $88 x .9 = $79.20
The probabilities of all possible outcomes in a distribution must sum to 1.

Answer:
-3, 1
Step-by-step explanation:
f(x) = 3(x − 1)(x + 3)
To find the x intercepts, set the equation equal to zero
0 = 3(x − 1)(x + 3)
Using the zero product property
x-1 = 0 x+3 =0
x=1 x=-3
