Answer:
c. 106 million
Step-by-step explanation:
A = number of people in the sample that use public transportation 5 or more days per week
A = 2,067,153
B = number of people total in the sample
B = 4,295,280
C = proportion of those in the sample that use public transportation 5 or more days per week
C = A/B
C = (2,067,153)/(4,295,280)
C = 0.48126 approximately
Multiply this value by the figure 220 million to compute the estimated number of people who use public transportation 5 or more days per week
C*(220 million) = 0.48126*(220 million) = (0.48126*220) million = 105.8772 million = 106 million
Step-by-step explanation:
j=25+5
j=30
final answer is 30
The expression that represents the cost of y books is 12y + 3.
Given that,
- The charge for the first copy of the book is $15.
- For each extra copy, the charge is $12.
- Here we assume the number of books be y.
Now based on the above information, the expression should be
= 12y + (15 - 12)
= 12y + 3
Therefore we can conclude that option F is correct.
