1)
36/3 x 42/3 = 12yd x 14yd
12×14=168
you will need 168 square yards to recarpet the kindergarten.
2)
168×24.99=4198.32
it will cost $4198.32 to recarpet the kindergarten.
3)
3.5 is 35% of 10
4198.32÷3.5=1198.52
they will need to sell 1199 coupon books to completely pay for the the recarpeting.

Answer:
The expected value per customer = $6.35.
Step-by-step explanation:
The probability for a $3 commission = 15% = 0.15.
The probability for a $5 commission = 30% = 0.30.
The probability for a $8 commission = 55% = 0.55.
So, the expected value per customer = 3(0.15) + 5(0.30) + 8(0.55)
= 0.45 + 1.50 + 4.40
= 6.35.
Hence, the expected value per customer = $6.35.
