Answer:

17% off $35

Step-by-step explanation:

The reason I say 17% off $35 is better price is because you get $5.95 off the original price.

So how did you do it they wonder, well in order to find out how much we are going to be taking off of a number as a percentage we have to turn 17% and 12% into a decimal by multiplying 17% and 12% by 100.

17% * 100 = 0.17

12% * 100 = 0.12

Now we multiply 0.12 by $32 and 0.17 by $35 in order to find out how much money you are saving:

0.12 * $32 = $3.84

0.17 * $35 = $5.95

So since $5.59 is bigger than $3.84 you have your answer 17% off $35 is a better price.

When renting a limo for prom, the number of people varies inversely with the cost per person. Originally there were 4 people and
ioda

Answer:The new cost per person= $19 when there are 12 people

Step-by-step explanation:

Step 1

Let Number of people be rep as N

And Cost per person = C

such that the relationship of  number of people which varies inversely with the cost per person is given as

N∝ 1/C

Introducing constant of proportionality, k, we have that

N= K/C

such that when there were 4 people the cost per person was $57, K would be

N= K/C

4 = K /57

k= 57 X 4

k=228

Step 2

Therefore If the number of people changed to 12, cost per person would be

N= K/C

12= 228 / C

C= 228/12

C= 19

The new cost per person= $19 when there are 12 people

What is the scale factor of the dilation
Marizza181 [45]
Looking at how the image shrinked from the original, you can assume that the scale would be a fraction. Since they remained negative, then the fraction wouldn't contain a negative. Therefore the answer would be C.

-2x + 6y = 6<br> -7x + 8y = -5
AleksandrR [38]

Answer:

x=-2\\y=2

Step-by-step explanation:

-2x+6y=6\\-7x+8y=-5

Let's multiply the first equation by 7 and the second equation by -2

(7)(-2x+6y=6)\\(-2)(-7x+8y=-5)

-14x+42y=42\\14x-16y=10

Now add them together. In this step, x is eliminated.

26y=52

Divide by 26.

y=\frac{52}{26}\\ y=2

Now plug this into any of the two equations to find x.

-2x+6y=6\\-2x+6(2)=6\\-2x+12=16\\-2x=16-12\\-2x=4\\x=\frac{4}{-2}\\ x=-2
