Answer:
Notebook is $4
Thumb drive is $23
Step-by-step explanation:
Let notebooks be x and thumb drives be y
6x+7y=$185
14x+12y=$332
These two are simultaneous equation. Multiplying the first equation by 7 and second by 3 we obtain
42x+49y=$1295
42x+36y=$996
Subtracting the third equation from the fourth
996-1295=-$299
(36-49)y=-23y
-23y=-$299
y=$299/13=$23
To get the value of x, we substitute the value of y into the first equation
6x+(7*23)=$185
6x=$185-$161
6x=$24
x=$4
Therefore, price of notebook is $4, price of thumb drive is $23
You need to find the slope too.
![m = \frac{y2 - y1}{x2 - x1} = \frac{ - 3 - 1}{0 - 4} = \frac{ - 4}{ - 4} = \frac{1}{1}](https://tex.z-dn.net/?f=m%20%20%3D%20%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20%20%3D%20%20%5Cfrac%7B%20-%203%20-%201%7D%7B0%20-%204%7D%20%20%3D%20%20%20%5Cfrac%7B%20-%204%7D%7B%20-%204%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B1%7D%20)
point slope formula y - y1 = m(x - x1)
use (0, -3)
y - (-3) = 1 (x -0)
y + 3 = 1x
Answer:
if she cannot spend more than $40, she will spend .3 on each cupcake
Step-by-step explanation:
when you divide 12 by 40, you get .3 and to check if it is true, you can multiply .3 x 40 and you will get 12 hope you get it right, and have a good day :)
