At a book fair, Scott bought a $4 tote bag and some books for $2 each. If he writes a linear function relating the number of books that he bought to the total amount that he spent, which will represent the rate of change in the equation?

Select one:

the cost for one book

the total amount spent

the number of books bought

the cost of all the books bought

  The total amount spent!

Step-by-step explanation:

So if you wanted to know how much he spent on books then you already Know the tote bag cost 4$ Then the books he bought cost 2$ each so that is why you need to know the total amount spent!

what is the starting amount? the question is not clear sorry.

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
