Answer:
the 360 g is the best deal because it is 1.28 per 1g
Step-by-step explanation:
Convert $4.10 and $2.81 to pennies
To do that we multiply them by 100 since there are 100 pennies per $1.
$4.10 x 100 = 410¢
540g/410¢ = 1.41¢
1.41 rounded is 1¢
then
multiply $2.81 x 100 = 281¢
360g/281¢ = 1.28 rounds to 1¢
There's a fixed difference of 6 between terms (9 - 3 = 6, 15 - 9 = 6, and so on). The first term of the sequence is 3, so the -th term is
If there are 24 terms in the sum, then the last term is 6×23 - 3 = 135.
Let be the sum,
Reverse the order of terms:
If we add up the terms in the same positions, we get twice on the left side, while on the right side we observe that each pair of terms will sum to 138.
and since there are 24 terms in the sum, the right side is the sum of 24 copies of 138. In other words,
and solving for gives
