Answer:
$9 for 36
Step-by-step explanation:
Divide the price by the quantity to receive the unit price. Here are the unit prices for each option:
1. $0.54
2. $0.43
3. $0.31
4. $0.28
5. $0.25
Basically, you want the lowest price. So, $9 for 36 is the best value because it costs $0.25 per pen.
Sin 39 = 8.9 / RT
RT = 8.9 / sin 39 = 14.14
cos 54 = RS / 14.14
RS = 14.14 * cos 54 = 8.3 cm Answer
Most of them are +10 because for example 8+10 is 18
