Problem would be $424 x .40
and the answer would be <span>169.6 USD</span>
If $1 is 5%, 100% would be $1 times 100/5= $1 times 20 = $20
Answer:
$52
Step-by-step explanation:
Using the equation
y=mx+c
82=7x+c
122=11x+c
11x-7x=122-82
4x=40
x=10
To get c
82=7(10)+c
82-70=c
c=12
For 4 lessons
y=10(4)+12=52
A is your answer tell me if I am wrong.
