just use a calculator or do ~long division~
Answer: at new cost increase is 30%
after additional $4.50 fee increase would be 45%
Step-by-step explanation:
use equation
30:100=39:x
30x=3900
x=3900/30
x=130
130-100=30%
39+4.50=43.5
30:100=43.5:x
30x=4350
x=4350/30
x=145
145-100=45%
-3 is your the answer a negitive times a negitive is a positive

Answer:$99.25
Step-by-step explanation:
Each by a sweatshirt including Amanda 3x25.50=$76.50 ,2 of them by popcorn so 2x4.75=$9.50, Amanda buys a hotdog 1x3.50=3.50, One friend bought nachos so 1x3.00=$3.00 and then Each girl bought a drink so 3x2.25=$6.75.
You have to add up all the totals which is 76.50+9.50+3.50+3.00+6.75 once you add those you get $99.25 that’s the total amount spent at the game.
Well, a distance-preserving transformation is called a rigid motion, and the name suggests that it <em>moves the points of the plane around in a rigid fashion.</em>
A transformation is distance-preserving if the distance between the images of any two points and the distance between the two original points are equal.
If that's confusing, I get it; basically if you transform something, the points from the transformation are image points. Take the distance from a pair of image points, and take the distance from a pair of original points, and they should be the same for a <em>rigid </em>motion.
I keep emphasizing this b/c not all transformations preserve distance; a dilation can grow or shrink things. But if you didn't go over dilations, don't say nothin XD
