Answer: 120 beats per 45 seconds
Step-by-step explanation:
Answer is 602 because we just take 301 times 2 because there is only two types of book in company and 301 book are ordered in each type so we just take 2 times 301
5 x 3 = 15 different solutions/combinations
1a, 1b, 1c, 1d, 1e
2a, 2b, 2c, 2d, 2e
3a, 3b, 3c, 3d, 2e
with the numbers representing the (3) crusts, and the letters representing the (5) toppings, 15 combinations would be the answer.
