So we solve for each
70% of 100=70
students who didn't buy lunch=100-70=30
some of the 70 left so that the students who bought lunch, are 60% of those who are left
we know that the students who didn't buy lunch didn't change number so therefor
100% of students left-60%=40%= students that didn't buy lunch=30 so
40%=30
20%=15
100%=75
there were 75 students lfet in the cafeteria
Answer: 2
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
The slope intercept form is y=1.38x
A higher positive slope means a steeper upward tilt to the curve, which you can see at higher output levels. A negative slope that is larger in absolute value (that is, more negative) means a steeper downward tilt to the line.
Answer:
-4/5 or -0.8
Step-by-step explanation:
Slope: (y2 - y1)/(x2 - x1)
m = (49 - 45)/(5 - 10)
= 4/-5
= -⅘
