4 groups of 6 and 5 students left over to eat
Answer:
15%
Step-by-step explanation:
$45/$300 = 0.15 = 15%
A plot would be very useful to solve the question.
0.8333
2/3 + x
x + 2/3
x + 2/3 = 3/2
x + 2/3 - 3/2 = 0
2/3 - 3/2 = 4/6 - 9/6 = - 5/6
x - 5/6 = 0
use linear function
f(x) - ax + b
f(x) = x - 5/6
a = 1
b = - 5/6
x- 5/6= 0
x = 5/6
x = 0.8333
