Answer:
The cost of 1 videotape = $ 3.4
Step-by-step explanation:
Let us assume the cost of each cassette tap = $ m
So, the cost of each videotape = 2 x ( Cost of 1 cassette) = 2 x m = 2 m
Now, the cost of 3 cassette tap = 3 x ( Cost of 1 cassette) = 3 x m = 3 m
Also, the cost of 5 videotape = 5 x ( Cost of 5 videotape) = 5 x (2m) = 10 m
So, the cost of 3 cassette tap + 5 videotape = 3 m + 10 m
Also, given 3 blank cassette tapes and 5 blank videotapes costs $22.10 .
⇒ 3 m + 10 m = $22.10
or, 13 m = 22.10
⇒ m = 22.10/13 =1.7
or, m = $1.7
Hence, the cost of 1 cassette = m = $1.7
And, the cost of 1 videotape = 2 m = 2x ($1.7) = $ 3.4
Answer:
0 Siblings: 4 Students
3 or more siblings: 5 students
Step-by-step explanation:
The numbers at the bottom represents how many siblings they have and the dots represent the number of studens so using this we know:
0 Siblings: 4 Students
1 Sibling: 3 Students
2 Siblings: 3 Students
3 Siblings: 1 Student
4 Siblings: 0 Students
5 Siblings: 2 Students
6 Siblings: 1 Student
7 Siblings: 1 Student
3 or more: 1 + 0 + 2 + 1 + 1 = 5
3 or more siblings: 5 students
