Answer:
341.5 because it makes the most sense
Answer:
it is 900
Step-by-step explanation:
3+6x+3x+ 6 = 180
9x + 9 = 180
9x = 171
x = 19
profit=f(x)
so solve for f(x)=1000
1000=70n-400
add 400 to both sides
1400=70n
divide both sides by 70
20=n
20 students need to be enrolled to make a profit of 1000.00
