Answer:
- late only: 15
- extra-late only: 24
- one type: 43
- total trucks: 105
Step-by-step explanation:
It works well when making a Venn diagram to start in the middle (6 carried all three), then work out.
For example, if 10 carried early and extra-late, then only 10-6 = 4 of those trucks carried just early and extra-late.
Similarly, if 30 carried early and late, and 4 more carried only early and extra-late, then 38-30-4 = 4 carried only early. In the attached, the "only" numbers for a single type are circled, to differentiate them from the "total" numbers for that type.
__
a) 15 trucks carried only late
b) 24 trucks carried only extra late
c) 4+15+24 = 43 trucks carried only one type
d) 38+67+56 -30-28-10 +6 +6 = 105 trucks in all went out
For this case, we must find the equation of the line.
The generic equation of the line is:
The slope of the line is:
Substituting values we have:
Rewriting:
We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:
Rewriting the equation:
For 20 visits, we evaluate the equation when x = 20.
We have then:
Answer:
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits

Answer:
<h2>39.25</h2>Step-by-step explanation:
Given the expression -8(2.5c-4.25)+5.25. On expansion;
.
The resulting expressing after expanding is . The constant value in the expression is the value that has no variable 'c' attached. The value of the constant term is therefore 39.25
