Answer:

y = -4x - 1

Step-by-step explanation:

x - 4y = 24

-4y = -x + 24

y = 1/4x - 6

m⊥ = -4

y = -4x + b

7 = -4 ( -2 ) + b

7 = 8 + b

b = -1

y = -4x - 1

Morgan’s grandmother orders her groceries online and has them delivered to her house. Her bill is $120. She has a coupon for 20%
iragen [17]

Answer:

The total price of the groceries, including discount and tip is $110.4.

Step-by-step explanation:

Here, the bill amount of groceries   = $120

Now, the coupon off  = 20%

Calculating the discount, we get

20% of bill amount $120  =   20% of 120  = \frac{20}{100}  \times 120  = 24

So, the 20% discount on the bill amount = $24

The actual payable amount = Bill Amount  - Discount

                                                =  $120 - $24  = $96

Now, 15% tip is also applied on the actual payable amount $96.

15% of 96 = \frac{15}{100}  \times 96  = 14.4

So, the total price t  = Payable amount + Tip amount

                                 = $96 +  $14.4   =  $110.4

or, t = $110.4

Hence, the total price of the groceries, including the discount and the tip  is  t = $110.4.
