Answer:
Total amount he paid = $45.62
Step-by-step explanation:
Number of packs purchased = 15
Cost per pack = $3.79
Total cost = 3.79*15 = $56.85
Since he purchased more than 10 packs, he gets a discount of 25%.
So, net cost after discount = 56.85*(1-0.25) = 42.6325
There is a sales tax of 7% on this amount
So, net cost after discount and sales tax = 42.6325*(1+0.07) = $45.62
Total amount he paid = $45.62

Step-by-step explanation:
The graph passes the vertical line test, so is the graph of a function (yes). Each input value has exactly one output value.
Answer:
(a-c)/b = x
Step-by-step explanation:
a = bx + c
subtract 'c' from each side to get:
(a-c) = bx
divide each side by 'b' to get:
(a-c)/b = x
5 + (-10) = 5 - 10
= -5 .
5 + (-3) = 5 -3
=2 .
5 + 3 = 8 .
5 + 0 = 5 .
Answer:
10
Step-by-step explanation:
3^2 + 3(6 − 2^2) ÷ 6.
PEMDAS says parentheses first
Calculate inside the parentheses
3^2 + 3(6 − 4) ÷ 6.
3^2 + 3(2) ÷ 6.
Then exponents
9 + 3(2) ÷ 6.
Then multiply and divide from left to right
9+6 ÷ 6.
9+1
10
