the pattern for the total earnings each week is an increase of $60
Explanation:
From the table, each week the earnings increased by certain amount.
We need to determine the amount.
earning in week 2 - earnings in week 1 = 180 - 120
= 60
earning in week 3 - earnings in week 2 = 240 -180
= 60
earning in week 4 - earnings in week 3 = 300 - 240
=60
Fromthe above, we can see the change in earnings is constant.
It increases by $60 every week
Hence, the pattern for the total earnings each week is an increase of $60
