Step-by-step explanation:
The tip they leave is ...
$78.64 × 0.20 = $15.73
The amount of the discount is ...
$78.64 × 0.15 = $11.80
Then the total cost of the meal and tip is ...
meal price - discount + tip
$78.64 -11.80 +15.73 = $82.57
2^3
the third choice is correct
Answer:

4.0+8.0=12.0-2.0=10.0
The equation computed shows that the number of days until both containers have the same weight of food in them will be 12 days.
<h3>How to calculate the equations?</h3>
From the information given, the instructions say to feed the old dog 2/3 pound of food each day from the bin with 25 lbs of kibble in it. the equation will be:
= 25 + 2/3d
= 25 + 0.67d
Also, the puppy is to get 1/4 pound of food each day from the bag with 20 lbs of puppy kibble in it. This will be:
= 20 + 1/4d
= 20 + 0.25d
The number of days until both containers have the same weight of food in them will be:
25 + 0.67d = 20 + 0.25d
0.67d - 0.25d = 20 - 25
0.42d = 5
d = 5/0.42
d = 11.9
d = 12 days
