Answer:
x=6, x=-8
Step-by-step explanation:
2|x+1|=14
|x+1|=14
Solve from there.
For each, it's easier to find what one item costs.
$6 for 3 = 6 divide by 3 = $2 per item
$9 for 6 = 9 divide by 6 = $1.50 per item
$10 for 8 = 10 divide by 8 = $1.25 per item
$1.40 per item
The best deal for lowest price per item is the $10 for 8
Answer:

Step-by-step explanation:
Let
denotes initial and final mass.

According to exponential decay,

Here, t denotes time and k denotes decay constant.

So, half-life of the goo in minutes is calculated as follows:

Half-life of the goo is 49.5 minutes

So,

Put 

Put t = 32 minutes
