Answer:
Step-by-step explanation:
First it base times height times (1/2)
The base is 7 boxes
The height is 5 boxes
A=(7)(5)(1/2)
A=(35)(1/2)
A=17.5
She is correct.
She starts with 50
Each square foot adds 3 dollars...
so Square feet can be represented by x, and cost will be y... giving this linear function:
