Answer:
5.3
Step-by-step explanation:
(x − 6)(x + 0.7) = 0
using the zero product property
x-6=0 x+.7 =0
x-6+6 = 0+6 x+.7 -.7 = 0-.7
x = 6 x= -.7
sum of the solutions
6+-.7 = 5.3
The probability of multiple events happening is found by multiplying the probabilities of each event together.

So yes, 1/10 is the answer :)
You have to add the $51 to $13 and find the answer then divide the sum by $28,500
