Answer:

C(t)= D-(30Dt/100)

Step-by-step explanation:

C(t)= 120-(30*120*1h)/100   C(t)=84

C(t)= 120-(30*120*2h)/100   C(t)=48

C(t)= 120-(30*120*3h)/100   C(t)=12

Write an expression for the apparent nth term(a) of the sequence. 2,5,8,11,14...
ExtremeBDS [4]

Answer:

Step-by-step explanation:

Since the sequence is increasing by a constant factor (3) each time, we know that this is an arithmetic sequence.

The formula for an arithmetic sequence is the following:

a_{n} = a_{1} + (n - 1)d

Where n is the number in the sequence and d is the constant that the sequence is increasing by.

Based on all of the information given, we know that a_{1} = 2 (since 2 is the first number in the sequence), and d = 3, so we can construct the formula:

a_{n} = 2 + (n - 1)3

a_{n} = 2 + 3n - 3

a_{n} = 3n - 1

sean rented an SUV for 2 days and drove it 430 miles the daily rate was 46.99 and .35 per mile with the first 50 miles being fre
pishuonlain [190]
So, to solve this problem you just have to add up all of the smaller parts.

First, we have our daily charge: $46.99
2 * 46.99 = $93.98

Next, we have our mileage costs, which will be
[ (miles driven) * (charge per mile) ] - (50 * 0.35)
(430 * 0.35) - 17.5
150.50 - 17.50 = $133

Finally, we add our daily rate to our mileage costs.
93.98 + 133 = $226.98
