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
AT&T= 2 years Verizon= 7 years, I hope this helps
Given 2 points compute the slope m. then write a point slope form
y-y1=m(x-x1). solve this for y
y=mx - mx1 +y1
27⅛ ÷ 3½
in my opinion, turning it into a decimal is easier
27 ⅛ = 27.125
3 ½ = 3.5
so.....
27.125 ÷ 3.5 = 7.75 which is also 7 ¾
