Sn = (n/2)(a1 + L)    where a1 = first term and L = the last.

-480 = (20/2) ( -81 + L)

-480 = 10( L - 81)

L- 81 = -480 / 10 = -48

L = -48 + 81

L = 33.

fenix001 [56]
"<span>9 1/4 ounces of fertilizer, 3/4 ounce of fertilizer for each plant."

Divide the total amt. of fert. by the amt. that goes to each plant:

9 1/4 oz
-----------------------
(3/4) oz per plant

Convert 9 1/4 to an improper fraction:  9 1/4 = 37/4.

Now divide 37/4 by 3/4, or divide 37 by 3.  Result:  12 1/3 plants.

Ms. Marks can fertilize 12 plants and have 1/3 oz of fertilizer left over.</span>
