Answer:
234
Step-by-step explanation:
We want to find the summation from n = 2 to n = 10 of the equation -4 + 5n.
We can use the summation formula:
, where a1 is the first term,
is the last term, and n is the number of terms
Here, we can say the first term occurs when n = 2:
-4 + 5n
-4 + 5 * 2 = -4 + 10 = 6
The last term will be when n = 10:
-4 + 5n
-4 + 5 * 10 = -4 + 50 = 46
The number of terms is just 10 - 2 + 1 = 9 terms.
Substitute these in:


Thus, the answer is 234.

Answer:
75%
Step-by-step explanation:
For this case, the first thing we will do is name variables:
a: percentage from ticket sales
b: ticket sales
We have then:
a = 75%
b = (0.75) * (3200) = $ 2400
Answer:
a = 75%
b = (0.75) * (3200) = $ 2400
The amount of ticket sales is $ 2400.
