1 quart is 2 pints so 1 would be 2 would be 4 3would be 6 etc so for the graphs the coordinates would be (1,2) (2,4) (3,6) etc..
Total cost=variable cost+fixed cost
variable cost=1.25 times x or 1.25x
fixed cost=3
y=1.25x+3
f(x)=1.25x+3 is da rule
65 = l - 15d; continuous
65 is the loaf of bread, and -15d is when Diep cuts 15cm of the bread for his lunch.
The graph is continuous because it is following a decreasing pattern of -15 per day. If the information were put on a data graph the line formed would be straight.
72 miles is how much he would run
