$20.50 x .3 = 6.15
20.50 - 6.15 = $14.35
The book is now $14.35
Answer: -15
Step-by-step explanation:
Let the unknown number be 'x'
Using the statement we can form the equation:
4 + x = -11
Now, solve the above equation to get :
4 + x = -11
x = -11 -4
x = -15
The number is -15. To check our answer, substitute for x :
4 + (-15) = -11
4 - 15 = -11
The above equation is correct. Therefore, the number is -15.
