Question

A roll of quarters contains 40 quarters and a roll of dimes contains 50 dimes. James has a jar that contains 83 quarters and 159 dimes. Lindsay has a jar that contains 129 quarters and 266 dimes. James and Lindsay pool these quarters and dimes and make complete rolls with as many of the coins as possible. In dollars, how much are the leftover quarters and dimes worth?

Answer 1

the question is to find out leftover money
Lindsay's jar contains 129 Quarters and other jar contains 83 quarters
add them
129+83= 212
each roll of quarters contains 40 quarters
so divide 212 by 40 that will give you 5.3 that represents 5 roll of quarters and 3 quarters leftover
same way to find dimes can you do that ?

Answer 2

hmm wait there is a typo

Answer 3

@S4Sensitiveandshy

I tried doing that I got 205

what i did was i realized the maximum # of rolls was 5

212-200 = 12
425-250 = 175

12*25 + 1750 = 2050 = $205

but Alcumus on AopS said it was incorrect...

Answer 4

because each quarter worth .25 not 25 ;)

Answer 5

OH I SEE

12*0.25 + 175 = 178

would that be the answer?

Answer 6

in my first I meant to say 3 dollar is leftover not quarters
212 subtract 12
200 is divisible by 40 so I get 5 (roll of quarters )
and 12 quarters
12 times .25 = 3 dollar

Answer 7

do you mean 178 leftover money ?? :o

Answer 8

yup...

Answer 9

hmmm no that's not correct
the total money is not even equal to 178
each dime worth .10 cents only

Answer 10

then 20.5?

Answer 11

can you please show how did you get 20.5 ?

Answer 12

212-200 = 12
425-250 = 175

12*0.25 + 175*0.1 = 20.5

Answer 13

why did you subtract 250 from 425 ?? :o

Answer 14

because there needs to be 5 rolls total at max... since 40 can only go into 212, 5 times. (40*5 = 200)
and then so that means 50 (the dimes)*5 = 250 dimes... the total number of dimes is 425 so 425-250 dimes = 175 dimes

Answer 15

hmm but 425-250=175
175 is 100+75 where 100 is also divisible by 50 right ?

the simple and easy way is to divide 425 by 50 or subtract 425-25=400
400 is also divisible by 50 so the left over is 25 dimes

Answer 16

OHHH i read it wrong i apologize haha
i was thinking of it as 40 quarters and 50 dimes make a roll, not separately

Answer 17

ohh I see you can't put dime into quarter roll ;) that would be cheating

Answer 18

so the answer is $55 correct??

12*25 + 25*10 = 550 cents = 55 dollars

Answer 19

okay if I give you 12 quarters and 25 dimes are you gonna be happy would that worth 55 dollars ?? ;) :P

Answer 20

wait a sec

Answer 21

oops 5.50

Answer 22

5.50 is right :))) THANKS FOR ALL YOUR HELP!!!

Answer 23

looks good :D 12 quarters that would be $3
and 25 dimes that would be 2 dollar and 50 cents and then add
3+2.50 would be 5 dollar and .50 cents

Answer 24

haha you're welcome :)
