Answer:
$30
Step-by-step explanation:
If x is the cost of a lesson, the total cost of Jodie's purchase is ...
cost of lessons + rental cost = total cost
12x + 25 = 385
12x = 360 . . . . . . . subtract 25
x = 30 . . . . . . . . . . divide by 12
Each violin lesson costs $30.
Your answer would be 6 because they scored 91, 91, 91, 94, 95, 95. Six grades equal 6 people!
Hope this helped!

Both expressions equal 5 when substituting 2 for x because the expressions are equivalent. Hope this helped :D

280 / 3500 = 0.08
