From the model,

Fatimah spent more than Sarin.

20 units = $1000

1 unit = $50

The amount that Fatimah spend more than Sarin

= 10× 50 = $500

Alternative solution:

3/5 spending of sarin is  1/5 spending of Fatimah

UPQ547-2

From the table,

Fatimah spent more than Sarin

The amount more that Fatimah spent = 15 – 5 = 10 units

20 units = $1000

The amount she spent more = 1000 ÷ 2 = $500
