Answer:
Step-by-step explanation:
When the problem says that Jake started by giving her $50, this means that initial money is a constant, it won't change, it already happened, it's invariable. So, that initial money is a constant term, a number without the variable.
Then, the problem specific that Jake will pay her $5 per week, but we don't know how many weeks are, so the unknown quantity, the variable <em>x </em>must represent "weeks", and this "weeks" must be multiplied by 5, because each of them represents $5 payed.
Therefore, the final equation is gonna be a sum of these two terms, the constant term and the variable term:
Where represents the total amount money payed by Jake after a <em>x </em>number of weeks.

Answer: 1. 0.0256
2. 0.4096
Step-by-step explanation:
Binomial probability formula , to find the probability of getting x successes:
, where n= Total number of trials
p= Probability of getting success in each trial.
Let x be the number of customers will make purchase.
As per given , we have
p= 0.20
n= 4
1. The probability that 3 of the next 4 customers will make a purchase will be:-
Hence, the probability that 3 of the next 4 customers will make a purchase = 0.0256
2. The probability that none of the next 4 customers will make a purchase will be :
Hence, the probability that none of the next 4 customers will make a purchase= 0.4096
