Answer 2

HI!!

Answer 3

is that page 44 that you posted?

Answer 4

hii and yes page 44 is the link

Answer 5

cause it looks like the answer to your question is right on the page

Answer 6

or maybe you are supposed to make up your own example

Answer 7

really?sorry I get confused easily about simple math stuff , I think you're right though

Answer 8

is this like a writing project to turn in or sommat?

Answer 9

we can make up a nice example easily, mimicking what they have done in their example

Answer 10

its just question no project

Answer 11

ok let's make one up, using the prices they have there

Answer 12

give me on second k?

Answer 13

ok

Answer 14

so we explain something then compare and contrast I think

Answer 15

yes that is what we will do

Answer 16

pick to items from the list they have with their prices
doesn't matter which two you pick

Answer 17

lol it doesn't matter which two you pick, but do it quickly because we don't want to spend like an hour doing this question
more like ten minutes tops

Answer 18

okay,the sale prices?

Answer 19

yes two items and their prices

Answer 20

don't pick the two they used pick others

Answer 21

used games and bargain games

Answer 22

ok good
used games cost $9.95, bargain $14.95 right?

Answer 23

yes

Answer 24

ok now lets say someone buys ten of each

Answer 25

how can we figure out the total cost?

Answer 26

dividing

Answer 27

that is the whole idea here, there are two ways to do it

Answer 28

lol no dear not dividing
you have to multiply
if you buy ten bargain games at $9.95 each, how much do you pay for those?

Answer 29

total i mean, how much do you pay total?

Answer 30

if you do not know, say "i do not know" a fine answer, and i will tell you

Answer 31

99.5?

Answer 32

yes !

Answer 33

which you get by \(10\times 9.95=99.5\)

Answer 34

now if you also by ten bargain games that cost $14.95 each, how much do you pay total?

Answer 35

got logged out, back now
you there?

Answer 36

@misty1212 149.5

Answer 37

yes

Answer 38

yea i got logged out too

Answer 39

now if you buy ten of each, ten used, ten bargain, we know the ten used cost $99.50 and the ten bargain cost $149.50
how much do you pay total ?

Answer 40

hint, use a calculator and add

Answer 41

249

Answer 42

right ok now here is the whole point of the question, ready?

Answer 43

ok

Answer 44

how did we get the $249? we got it by multiplying 9.95 by 10 and 14.95 by 10 and adding, i.e. we computed \[10\times 9.95+10\times 14.95=99.5+149.5=249\]

Answer 45

but there is another way to do it!

Answer 46

instead of multiplying each price by ten and then adding, we could have added first, them multiplied the result by ten

Answer 47

\[9.95+14.95=24.90\]first then \[10\times 24.90=249\]

Answer 48

that is the idea behind the distributive property
first multiply, then add \[10\times 9.95+10\times 14.95=99.5+149.5=249\] or first add, then multiply \[10(9.95+14.95)=10\times 24.9=249\]

Answer 49

I see the point now

Answer 50

ok then you can use that example, supply your own words, that answers the question
it is an example of \[ab+ac=a(b+c)\]where the left side was \[10\times 9.95+10\times 14.95\] and the right side was \[10(9.95+14.95)\]

Answer 51

nice watch btw

Answer 52

so how would we compare and contrast(sry if its obvious) and I didn't think I would get this but I do now ty for that

Answer 53

well, i would compare like this:
clearly you get the same answer, so it does not matter which method you use
in some cases it might be easier to use one, in some cases it might be easier to use the other
for example, if you wanted \[7\times 2.5+7\times 3.5\] it would probably be easier to add first and and compute \[7\times (2.5+3.5)=7\times 6=42\]

Answer 54

on the other hand, if someone bought 10 of one kind of game and say 7 of another, you could not do it by adding first, you would have to compute separately then add \[10\times 9.95+7\times 14.95\]

Answer 55

actually you can say pretty much anything you like i think once you worked out the specific example like we did above

Answer 56

Okay, I think I can answer the question fully now thanks to you! :) thank u again though because I had this question for 4 days lol, (thank u skullpatrol too)
