Question

Can you guys help me with something real quick? I'm a bit confused with this math homework. I'll give medals.

Answer 1

you can only give one meda. but shoot.

Answer 2

Imagine that a generous relative has agreed to give you $3 for every $2 you save. Use a part whole model to calculate how much of the savings goal will be yours to raise and how much you can expect the relative to contribute.

The numbers I have for the trip are: Actual cost: 8,100 Rounded cost: 8,800
I'm really confused on this.

Answer 3

spend $2 ------> make $3

now, what is this about the actual and total cost?

Answer 4

How much money would I need raise and how much will the relative provide for the trip?

Answer 5

i see
ok
lets say you raise "x"
then your relative should pay -> \(\Large {x\times 3\over2}\)

Answer 6

so, total expenditure = money you put in + provided by relative

total = x + \(\Large{x\times3\over2}\)

Answer 7

kapeesh?

Answer 8

OK.. I'm still confused.

Answer 9

let us start with the assumption that we put in "x" amount

Answer 10

OK

Answer 11

then the relative puts in a proportional amount:

for every "$2" that you put in, the relative contributes "$3"
so, for "$x" that you put in, the relative contributes ______

Answer 12

you see it?
the relative contributes \[x\times 3\over2\]

Answer 13

OK

Answer 14

gud.
then the total amount you've got: = the amount you put in + the amount from the relative

Answer 15

how much amount do you need in total?

Answer 16

So it's 9,000 x 3?

Answer 17

no wait.. we need to know how much we need in total

Answer 18

how much does the trip cost?

Answer 19

Well for the whole 3 trips I've 'planned' cost 5,500, 1,500, 1,100

Answer 20

i see
so you will need to raise a total of = 5500 + 1500 + 1100 = 8100
correct?

Answer 21

Wait the first one is 4,000 sorry. :\

Answer 22

ok, so how much do you need to raise in total then?

Answer 23

so it would be 4,000 + 1,500 +1,100 = 6,600
\

Answer 24

good.
this amount = amount you put in + amount relative puts in
\[6600=x+{x\times3\over2}\]
solve for "x"

Answer 25

x is 3?

Answer 26

what? no.. you have to solve for it.

Answer 27

So to solve it I have to divide right?
