Answer:
A
Step-by-step explanation:
55+20=75 and the other percentage is 25
Divide y by x:
150/10 = 15
135/9 = 15
30 /2 = 15
They all equal 15
This means the constant of proportionality would be y = 15x
The answer is C.
a_3 is 45 and a_10 is 98415
Step-by-step explanation:
Given
a_1 = 5
a_2 = 15
First of all we have to calculate the common ratio of the sequence. The common ratio is the ratio between two consecutive terms of a geometric sequence.
So,

The explicit formula for geometric sequence is:

Putting the value of r and a_1

Putting n=3 in the explicit formula

Putting n=10 for tenth term

Hence,
a_3 is 45 and a_10 is 98415

To find the cost of the truck, you will need to add all the expenses that incurred in addition to the actual cost of the truck.
35000 + 2000 + 1200 + 120 + 220 = 38540
The cost including expenses should be recorded as $38540.
