Answer:
12x + 15y = 120
Step-by-step explanation:
x= t shirts
y= sweatshirts
x+y=total
12x + 15y = 120
(I got this question on a quiz and I got it right!)
I hope this helps!
The equation 12x + 15y = 120 represents the total number of t-shirts and sweatshirts bought if spend $120
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The price for t-shirts = $12 each
The price for the sweatshirt = $15 each
Let's suppose x number of t-shirts and y number of sweatshirts bought.
Then,
12x + 15y = 120
The equation represents the total number of t-shirts and sweatshirts bought if spend $120
Thus, the equation 12x + 15y = 120 represents the total number of t-shirts and sweatshirts bought if spend $120
