John and Nat were given some money. 
If John spends $50 and Nat spends $100 each day, 
John would still have $2500 left while Nat would 
have spent all her money. 
If John spends $100 and Nat spends $50 each day, 
John would still have $1000 left while Nat would 
have spent all her money. 
How much were John and Nat given each?
John and Nat were given some money. 
If John spends $50 and Nat spends $100 each day, John would still have $2500 left 
while Nat would have spent all her money. 
If John spends $100 and Nat spends $50 each day, John would still have $1000 left 
while Nat would have spent all her money. 
How much were John and Nat given each? 
STEP 1 : Draw an approximation of the amount given to John and Nat. It looks 
like John was given more money since he has money left whether he spends 
more or less per day compared to Nat. (Its not important to be exact here)

John and Nat were given some money. 
If John spends $50 and Nat spends $100 each day, John would still have $2500 
left while Nat would have spent all her money. 
If John spends $100 and Nat spends $50 each day, John would still have $1000 left 
while Nat would have spent all her money. 
How much were John and Nat given each? 
STEP 2 : We know Nat spends 2 times more than John in the first scenario. 
Lets draw equal blocks to represent this understanding.

left while Nat would have spent all her money. 
How much were John and Nat given each? 
STEP 4 : Lets model for the second scenario. This time, John spends 2 times more 
than Nat. Since in both scenarios, Nat spends all her money, Nats yellow bar 
would still be the same length, and John would have 2 times as many squares

while Nat would have spent all her money. 
How much were John and Nat given each? 
STEP 6 : At this point, we can compare the 2 scenarios for John and find the value 
for each block! Can you find it?

If John spends $100 and Nat spends $50 each day, John would still have $1000 left 
while Nat would have spent all her money. 
How much were John and Nat given each? 
STEP 7 : First, compare the white block in scenario 1 with the same length in 
scenario 2. We can tell that 3 Units + $1000 = $2500.

while Nat would have spent all her money. 
How much were John and Nat given each? 
STEP 8 : Therefore, 
3 Units = $2500-$1000 = $1500. 
1 Unit = $1500 / 3 = $500

STEP 8 : Since we draw equal units, we can easily calculate John was given 
4 units + $1000 = (4 X $500) + $1000 = $3000

STEP 10 : Now, lets check our answers by applying the answers to the original 
scenarios.

Scenario 1 : 
Nat has $1000, and spends $100 per day. She will take 10 days to spend $1000. 
In 10 days, John would spend $50 X 10 days = $500, and have $2500 left. This adds 
up to $3000 which matches our answer.

up to $3000 which matches our answer. 
Scenario 2 : 
Nat has $1000, and spends $50 per day. She will take 20 days to spend $1000. 
In 20 days, John would spend $100 X 20 days = $2000, and have $1000 left. This 
again adds up to $3000 which matches our answer. So we can safely say our 
answer is correct!
