Answer:
25x + 65y = 80
Step-by-step explanation:
Total amount to be spent = $80
Maximum amount to be spent on music = $25
Maximum amount to be spent on books = $65
Let x represent music and y represent books
x(25) + y(65) = 80
25x + 65y = 80
The equation that represent the situation is
25x + 65y = 80

Answer:
y=x-3/15
Step-by-step explanation:
f(x)=15x+3/y=15x+3
f-1(x) is an inverse function, which means you gotta swap the x an the y:
x=15y+3
The goal is to get y alone, so you minus 3 on both sides to get
x-3=15y
And then divide both sides by 15 to get y alone
x-3/15=y
