Answer:
-1
Step-by-step explanation:
We need two points to use the slope formula
(0,2) and (2,0) are points on the line
m= ( y2-y1)/(x2-x1)
= (0-2)/(2-0)
= -2/2
=-1
Answer:
45 mins
Step-by-step explanation:
The question is how much time should the painter spend on painting a doll for the costs to still be equal or lower to $24.50
We can make this equation, representing the raw materials + the painting job (at $18/h):
$11 + $18x = $24.50
18x = 13.50
x = 13.5 / 18 = 0.75
So, the painter should spend at most 3/4 of an hour (or 45 mins) painting a doll to keep the cost at or below $24.50 per doll.
