Hey there!
First we need to find the unit rate of each sweatshirt then multiply that by 5
To find the unit rate, just divide $45 by 3
45 ÷ 3 = 15
So now we know that each sweatshirt costs $15
Now, we can multiply $15 by 5
15 x 5 = 75
Therefore, 5 sweatshirts would cost $75
Hope this helps you!
Always remember you are a Work Of Art!
