Let the number of people be x.
Total tips = 3.5x
Total cost = 750
Each person = $15
15x = 750 + 3.5x
15x - 3.5x = 750
11.5x = 750
x = 65.22
Answer: 66 people should participate.
Answer:
1. 32
4:4 is the same as 1:1 meaning each one gets the same
2. 40
put 1/7 equal to 5/x and cross multiply (1x=35)(35 male workers, so add 35 to 5 female workers)
3. 8
Multiply two by 4 since an hour is 15×4
4. 188
put the ratio 7/330 to 4/x (7x=1320)(x=188.57) since you can use part of a nail, round down to 188.
5. 5 1/2 pounds
multiply 1/4 by 22 which is 22/4. that is equal to 5.5
19500 times because
5 times 26 = 130 (how many minutes)
and
now just multiply how many minutes (130) times how many heart beats per minute (150) to get 19500
