Upper primary school mathematics question UPQ552

Fatimah was given \$5 pocket money every day. The line graph below shows the total amount of savings she had at the end of each day for a particular week.

a.        How much did Fatimah spend on Monday?

b.        On which two days did Fatimah save the same amount of money?

c.        What was the average amount she saved from Tuesday to Saturday?

Solution:

Per the line chart,

Saving on Monday = \$1

a.        Spend on Monday = 5 – 1 = \$4

Saving on Wednesday = 4.5 – 4 = \$0.5

Saving on Saturday = 8.5 – 8 = \$0.5

Therefore,

b.         Wednesday and Saturday have the same amount of saving.

Total Saving from Tue to Sat = 8.5 – 1 = \$7.50

c.        Average saving from Tue to Sat = 7.50 ÷ 5 = \$1.50
