3(x^2 +2xh + h^2) -4(x + h) -5
(3x^2 + 6xh + 3h^2 -4x -4h -5 - ( 3x^2 -4x -5))/h
(6xh + 3h^2 -4h)/h
h(6x +3h - 4)/h
6x + 3h -4
The slope would be -x+6 & m=-1

Answer:
11 coins for $1.99
Step-by-step explanation:
The maximum total less than $2 is $1.99. It takes 11 coins to make that total. It would take 1 fewer if the nickel were not required.
Starting with the minimum required coins, which total $0.91, we need to add $1.08 using a minimum number of coins. To minimize the added coins, we start with the largest we can use without going over the total: 2×50¢ + 1×5¢ + 3×1¢. These 6 coins added to the required 5 coins give the desired total using 11 coins.
11 coins: $1.99 . . . . (3×50¢ +1×25¢ +1×10¢ +2×5¢ +4×1¢)
$1.99 is the highest possible total less than $2.00, and it takes a minimum of 11 coins to make that total.
