Answer:17hrs
Step-by-step explanation:
520/8=65
1105/65
17
X is t shirt is $8
Y is sweatshirt $11
2x+2y=38
3x+1y=35
We will be using the elimination process so you want even them out same value
2x+2y=38
-6x-2y=-70 ( want get rid of the y-value by increasing to other by when both add or subtract it will equal 0)
-4x=-32
Divide both -4
X=8 So 8 dollars a t-shirt so now will fill x with 8
2(8)+2y=38
16+2y=38
-16
2y=22
Divid by 2
Y = 11 so a sweatshirt is 11 dollars
You can check by fill each by the variable
Yes, this is a function because the mapping is one to one. The domain is the the different inputs that can be put into the function, so the domain is {1,2,3,4,5}. The range is the different outputs the function can produce. So the range would be {40,80,120,160,200}.
