1 answer:

3 0

4x - 8y = 8
8y = 4x - 8
y = 1/2 x - 1

slope: 1/2
y-intercept:(0, -1)

Line perpendicular- negative reciprocal slope

y-(-1) = -2 (x-0) Hahaha I don't know what is the point slope form though hahaha not sure with this.

First, use division to determine the unit rate of one cookie (sorry if terminology is wrong, but i do know how to do it).

Little town = 9/$8 = $1.125 per cookie
College town = 30/$13 ≈ $2.3076 per cookie

Now we are sure of how much each costs and can determine how much she would have spent at each place.

Little town= $1.125*10= $11.25
College town= $2.3076*10≈ $23.08

Now, subtract little town from college town to figure out the savings.

23.08-11.25= $11.83

Thus, she saved $11.83.
