The correct answer is option B which is the system of equations will be
( x + y = 24 ) and ( 30x + 45 y = 16 ).
What is an equation?
The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
Given that:-
- A television network must air 16 minutes of commercials during a 1-hour show. All commercials aired on this network are either 30 seconds or 45 seconds. The network would like to run exactly 24 commercials during a certain 1-hour program. Which of the following systems could be used to determine the number of 30-second commercials, 2, and the number of 45-second commercials, y,
The equations will be formed as follows:-
1 ) Total number of the commercials so the equation will be given as:-
x + y = 24
2 ) The total time for the commercial to air on television is 16 minutes and the x has 30 seconds and y has 45 seconds so the equation will be formed as:-
30x + 45y = 16
Therefore the correct answer is option B which is the system of equations will be ( x + y = 24 ) and 30x + 45 y = 16.
