Answer:
The equations could be used to find one of the numbers is,
Step-by-step explanation
Let two integers be a and b.
As per the given statement:
The product of two integers is 112.
⇒ ......[1]
Also, One number is 4 more than three times the other.
⇒b = 3a +4 ......[2]
Now substitute equation [1] in [2] we get
Using distributive property i.e,
Simplify:
therefore, the equation that could be used to find one of the numbers is;

Answer: 60
Step-by-step explanation:
To solve this problem, you first have to figure out how many customers put 2 and how many customers put 1. To do this, you count the amount of 2's on the survey, which is 19. Then, you count the amount of 1's, which is 6.
Then, you divide both of them by 25, since that is the number of customers that were surveyed. 6 divided by 25 is 24% and 19 divide by 25 is 76%. Therefore, 24% of the customers were new.
So, you do 250 times 24% (or 0.24 in decimal form) and you will get 60.
So, there will be an estimated amount of 60 customers out of the next 250 that are new.
