$0.90
Step-by-step explanation:
7.20/8 = $0.90
Before sales tax he would have to pay $40 * (1 - 0.25) + $100 * (1 - 0.35) = $30 + $65 = $95.

Answer:
- the y intercept is 1
- the slope of this line is 1
- the equation of the line is y = x + 1
Step-by-step explanation:
First Take two coordinates the line is passing: ( 0 , 1 ) , ( -1 , 0 )
To find slope use: 
: 
: 1
Equation using: y= mx+b ...where m is slope and b is y intercept therefore:
Equation of the line:
y = x + 1
