Serena asked her parents if for their picnic they could have 20% more portions of coca-cola than they planned, and if each porti

jeyben [28]

Answer:

44%

Step-by-step explanation:

If p represents the number of portions and q represents the quantity in each portion, then the original amount needed was p·q.

After p is increased by 20%, its number is ...

p + 0.20·p = 1.20·p

After q is increased by 20%, its amount is ...

q + 0.20 ·q = 1.20·q

Then the new amount the parents must buy is ...

(1.20p)(1.20q) = 1.20²·pq = 1.44pq

This amount is ...

(1 + 44/100)·pq = pq + 44%·pq

It is 44% more than the original planned purchase.

Kendrick's Kennel has 2 spots for cats for every 7 spots for dogs. If he has a total of 144 spots for both cats and dogs,then ho

Keith_Richards [23]

Alright, lets get started.

Kendrick's Kennel has 2 spots for cats for every 7 spots for dogs.

Suppose spots for cats = 2x

So, spots for dogs will be = 7x

Total spots for cats and dogs will be = $2x + 7x$

Total spots for cats and dogs will be = $9x$

As per given in question, total spots for both cats and dogs are 144, so

$9x = 144$

Dividing 9 in both sides

$\frac{9x}{9} =\frac{144}{9}$

x = 16

So, spots for cats = $2 * 16 = 32$

Spots for dogs = $7 * 16 = 112$

So, spots for dogs more than cats are = $112 - 32 = 80$

It means he has 80 more spots for dogs than cats. : Answer

Hope it will help :)
