665/8 = 83.125
This means that in 1 year 1 person ate 83.125 pounds of potatoes.
Answer:
f(x) = -3x + 10
Step-by-step explanation:
Substitute values to find b;
y=mx+b
y=-3x+b
<em>Replace X and Y</em>
4=-3(2)+b
4=-6+b
<em>Swap sides to set equal to b. Swapping causes sign change</em>
4+6=b
10=b
110/55 is what u get if u add them all up
