Answer:
10 hotdogs for $5.00 is the better deal
Step-by-step explanation:
Let's find the price of 1 hotdog if 8 hotdogs cost $4.08.
$4.08 ÷ 8 = $0.51 per hotdog
Now let's find the price of 1 hotdog if 10 hotdogs cost $5.00.
$5.00 ÷ 10 = $0.50 per hotdog
$0.50 per hotdog is slightly cheaper than $0.51 per hotdog, so 10 hotdogs for $5.00 is the better deal.

Checking for a perfect cube
2.1 x3-2x2+2x-1 is not a perfect cube
Trying to factor by pulling out :
2.2 Factoring: x3-2x2+2x-1
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 2x-1
Group 2: -2x2+x3
Pull out from each group separately :
Group 1: (2x-1) • (1)
Group 2: (x-2) • (x2)
