A tutor works with a group of students. the tutor charges a base fee of $40 plus $30 for each student in the group. today the tutor has y students and charges a total of $220. write the equation and solve.

y=6

Step-by-step explanation:

Let's solve your equation step-by-step.

30y+40=220

Step 1: Subtract 40 from both sides.

30y+40−40=220−40

30y=180

Step 2: Divide both sides by 30.

30y/30= 180/30

y=6

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.
