Answer:
15 black water bottles
Step-by-step explanation:
let w represent white water bottles, and let b represent black water bottles.
set up a system of equations:
w+b=20
w+2b=35
(the top equation shows that the number of white water bottles he sold and the number of black water bottles he sold equals to 20, since it says that the total number of water bottles is 20. the bottom equation shows that white water bottles cost $1, and black water bottles cost $2, and that the total amount of money he got from selling them is $35).
in the top equation, isolate w:
w+b=20
w=20-b
now we do substitution. in the bottom equation, substitute 20-b for w:
w+2b=35
20-b+2b=35
then, solve:
b+20=35
b=15
this means that he sold 15 black water bottles.

The rate of the machine is 10 boxes per min.
Step-by-step explanation:
Given,
A machine can make 150 boxes in 15 min
To find the rate of the machine
Meaning to find the number of boxes machine it can make in 1 min
We will apply unitary method.
In 15 min it makes 150 boxes
In 1 min it makes (150÷15) boxes = 10 boxes
Hence the rate is 10 boxes per min.
