266,667 bottles
Step-by-step explanation:
80/300 people preferred soft drink z. This as a decimal is 0.2666This means that out of the million, 0.2666666666666667% need to be soft drink z
1,000,000x0.2666666666666667 =266,666.667
This can be rounded to 266,667 bottles of soft drink z
(I chose to include the whole decimal for the most accurate results, and save rounding for the last step)

answer:
the equation of given expression is 2(x+ 7) = 3x and the number is 14.
step-by-step explanation:
given : expression "twice the sum of a number and seven is three times the number."
we have to write the given expression first in equation form and then solve for the number.
consider the given expression "twice the sum of a number and seven is three times the number."
let the number be x , then
the sum of a number and seven written mathematically as x + 7
twice the sum of a number and seven written mathematically as 2(x + 7)
also, three times the number written mathematically as 3x
thus, the equation of given expression becomes,
2(x+ 7) = 3x
solve for x, we have,
2x + 14 = 3x
subtract 2x both side, we have,
3x - 2x = 14
x = 14
thus, the number is 14.
