To help solve this problem, create an equation.
Let x = number of notebooks
$30 = $22.50 + $1.50x. Subtract $22.50 from each side.
$7.5 = $1.50x. Divide each side by $1.50.
5 = x.

1: D. 1/336
Explanation:
10 x 9 x 8 = 720
There are 720 ways for them to come in first, second and third place.
2. Probability = 1/8 x 1/7 x 1/6 = 1/336
The probability is 1/336 or 0.002976.
Answer:
214°
Step-by-step explanation:
The arc subtending an angle at the centre are equal, that is
arc ED = 90° and
arc DF = 360° - (90 + 146)° = 360° - 236° = 124°
Thus
arc EDF = arc ED + arc DF = 90° + 124° = 214°
