Answer:
22 per dog when she is walking 8
she would make 176 for walking all 8 of them
Step-by-step explanation:
For each additional dog she walks she is giving a discount. If you subtract each one you will see she is giving a 2.75 discount.
40-37.25 = 2.75
37.25-34.50 = 2.75
34.50-31.75 = 2.75
Since you know she gives a discount of 2.75 per dog you can take that times the number of dogs (8).
8 x 2.75 = 22 per dog
Then take that amount and multiply it by the number of dogs she is walking.
8 x 22 = 176 for all 8 dogs
Answer:
1,712,304 ways
Step-by-step explanation:
This problem bothers on combination
Since we are to select 5 subjects from a pool of 48 subjects, the number of ways this can be done is expressed as;
48C5 = 48!/(48-5)!5!
48C5 = 48!/43!5!
48C5 = 48×47×46×45×44×43!/43!5!
48C5 = 48×47×46×45×44/5!
48C5 = 205,476,480/120
48C5 = 1,712,304
Hence this can be done in 1,712,304ways
