Y=mx+b
since the variable that will increase or deacrease is the number of books
then we set it to x
x=number of books
the member fee is constant so
b=10
the amount of money will increase by 5.99 per book so
m=5.99
the total amount of money will be our function since it depends on x
y=total amount of money
y=5.99x+10
total amount of money=5.99(number of books)+membership fee
It is $6 more now than before...maybe you were looking for percent increase?
%change=100(final-initial)/initial
%change=100(10-4)/4=150% increase
3. 60%
4. 5/8
5. 5/25
6. 62%
7. 70%
8. 40
9. 9
10. 22.5%
11. 70
12. i dont know that one sorry.
13. Written as an equation: Y = P% * X.
The 'what' is Y that we want to solve for.
Remember to first convert percentage to decimal, dividing by 100.
Solution: Solve for Y using the percentage formula. Y = P% * X.
Step-by-step explanation: just switch up a few words here and there on 13 and you should be good to go!
