Answer:
300 students
Step-by-step explanation:
Since 4/5 of students do not wear glasses, 1/5 of students do.
There are 60 students who wear glasses, so let 'x' represent the number of students who wear glasses
(1/5)x = 60 is our equation. "One-fifth of the number of students who wear glasses is 60"
Now solve for x
(1/5)x = 60
x = 300 (multiply both sides by 5 to get rid of the fraction)
Y-585 = -7.5(x-15)
y = -7.5x - 7.5(-15) + 585
y = -7.5x + 697.50
C = -7.5(52) + 697.50 = $307.50
Y=(x+7)/8
Work:
Y=8x-7 —> x=8y-7
Solve for y
x+7=8y
y=(x+7)/8
