The inequality is 1.5*x + 10*y ≥ 50, and the graph is in the image at the end.
How to model this situation?
We know that the variables are:
x = number of stickers they sell.
y = number of albums they sell.
Then the total revenue is given by the expression:
1.5*x + 10*y
And we know that they want to make at least $50, then we can model this with the inequality:
1.5*x + 10*y ≥ 50
Now let's graph it, we can isolate y to get:
y ≥ (50 - 1.5x)/10
To graph the inequality, you need to graph that line and shade the region above the line. The line must be solid because y can be equal to the points in the line.
Complete question:
"a band is selling stickers and albums at a concert the stockers sell for $1.50 each and the albums sell for $10 each the band wants to earn at least $50 from sales of stickers and albums let x represent the number of stickers and y represent the number of albums they sell.
Write and graph the inequality"
