Hi!
Each piece cost 1.95, then 1000 pieces will cost:
1000 * 1.95 = 1950

Answer:
3 can go into 77 25 times.
Make 2 equations from the question first
x is the number of pints for type 1
y is the number of pints for type 2
The equation
x + y = 120
60% x + 85% y = 65% (x + y)
Solve the equation
From the 2nd equation
0.6x + 0.85y = 0.65(x + y)
0.6x + 0.85y = 0.65x + 0.65y
0.85y - 0.65y = 0.65x - 0.6x
0.2y = 0.05x
y = 4x
From the 1st equation
x + y = 120
x + 4x = 120
5x = 120
x = 24
y = 4x
y = 96
The first type should be 24 pints, the second type should be 96 pints
5 x 10 is 50 then 50 + 11 is 61 so I think it would be 61 ;)
R; all quadratic functions are going to have ranges and domains of *ALL REAL NUMBERS*.
