Answer:
x + 3y = 15
The graph is attached below.
Step-by-step explanation:
Given the price of album = $10.
and the price of movies = $30.
Let's assume she buys "X" albums and "Y" movies.
Cost would be (10X + 30Y).
She plans to spend a total of $150, so cost would be same as total expenditure.
10X + 30Y = 150
X + 3Y = 15
we can graph this equation of line on a graph paper as given below:-
(x/3) + x =144
4x = 144 *3
x = (144/4) *3
x=36*3
x=108
The number is 108 :)
