Since 300 is 100%, you treat it as such.
300/(100/70) = 210 (rounded)
You do a similar thing for 600
1/4 of 100 is 25
100/25 = 4
600 / 4 = 150
70% of 300 is more.
We know that
An ordered pair is used to locate a point on a coordinate grid.
The first number in an ordered pair is the
x-coordinate, and the second number in an ordered pair is the
y-coordinate.
In this problem, the ordered pair is

so
the x-coordinate is equal to

the y-coordinate is equal to

therefore
Rule N 1The y-value is

times the x-value
Rule N 2The y-value is

greater than the x-value
Both are possible because their solutions include the ordered pair listed
The temperature at noon was 6 °F.
