Bess [88]

Answer:

The number of students attended was 334 and the number of non students attended was 127

Step-by-step explanation:

Let

x ----> the number students attended

y ----> the number of non students attended

we know that

$x+y=461$ ----> equation A

$3.50x+5.50y=1,867.50$ ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (334,127)

see the attached figure

therefore

The number of students attended was 334 and the number of non students attended was 127

Kelvin says that 22/30 is greater than 22/32 do you agree ? explain

kozerog [31]

When two fractions have the same numerators, the one with the smaller denominator is the greater fraction.

$30 < 32 \Rightarrow \frac{22}{30} > \frac{22}{32}$

So Kelvin is right.
