Amount of money

Question

The Griffin family puts their coins in a jar every times they get change from the store. They also take coins out of the jar when they need more money to buy something. On Monday, the jar had $50 in it. The chart below shows how the amount of money in the jar changed during one week.

 

Monday: No money added or taken away

Tuesday: Sarah puts in $10.50

Wednesday: Mira takes out $17.50

Thursday: Karen takes out $8.50

Friday: Tony puts in $15.25

 

How much did the amount of money in the jar change from Monday to Friday? Show how you got your answer

Answer 1

10.50 + 15.25 = 25.75 money added (From Tue, Fri)

17.50 + 8.50 = 26.00 money removed (From Wed, Thur)

 

25.75 - 26.00 = -0.25

 

Since we have a negative number, we have lost 25 cents.
