Sue is packing boxes for a removal company.
She packed 55 boxes in 5 hours. Since she is getting better at it, each hour she packs 2 more boxes than the previous hour.
How many did she pack in the last hour.
:
Let n = number of boxes packed in the 1st hr
:
n + (n+2) + (n+4) + (n+6) + (n+8) = 55
5n + 20 = 55
5n = 35
n = 7 boxes the 1st hr
then
7 + 8 = 15 boxes the last hr
