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

Answer:
15$
Step-by-step explanation:
Okey so first we establish that 25 is 100%

Then we times these numbers by 6 to find 60%
<u>60% = 15</u>
Matthew will earn <u>15$</u>
Luke will earn 10$
