Question

the sixth-grade class at west side school starts a charity collection on monday, with $78 donated by the parents organization. they plan to add $2 to the fund each day .how much will they have after 90 days?

Answer 1

y = 2x + 78.....y = total money collected, x = number of days

after 90 days.....x = 90
y = 2(90) + 78
y = 180 + 78
y = 258 <== after 90 days, they had $ 258

Answer 2

Class will have accumulated $258 after 90 days

The class plans to raise $2 every day. In 90 days therefore, they would have made:

= Amount per day x Number of days

= 2 x 90

= $180

The class had already been given $78 so the total they have is:

= Amount to be made from daily additions + Amount already donated

= 180 + 78

= $258

In conclusion, the class will have $258 after 90 days
