Answer:
30 c + 100 m = 700
c+ m = 14
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations.
The product of the number of movies where the song was played (m) multiplied by the earnings per movie (30) plus the product of the number of commercials where the song was played (m) multiplied by the earnings per commercial, must be equal to $700.
30 c + 100 m = 700
The number of movies (m) plus the number of commercials (c) is equal to 14.
c+ m = 14
The system is:
30 c + 100 m = 700
c+ m = 14
The total cost of the dinner meals taken by Arif and Keisha = $13.75
Percentage of tax that need to be given = 5%
Then
Amount of tax that needs to be given = (5/100) * 13.75 dollars
= 13.75/20 dollars
= 0.687 dollars
= 0.69 dollars
So
The total amount that needs to be
paid for dinner including tax = (13.75 + 0.69) dollars
= 14.44 dollars
Percentage of tips that they both want to leave = 15%
Then
Amount of tips that need to be given = (15/100) * 14.44
= 216.6/100 dollars
= 2.17 dollars
So
The total amount that they should leave = (14.44 + 2.17) dollars
= 16.61 dollars
So they should leave a total of $16.61 in the restaurant.
