Answer:

The total cost of the helicopter = $26.5

The cost of lithium battery = $5.

The amount of sales tax = $1.5

Step-by-step explanation:

We have been given that a radio-controlled helicopter sells for $20, but needs a lithium battery that costs 25% of that price.

We can find the price of battery by finding 25% of 20.

\text{The cost of lithium battery}=\frac{25}{100}\times 20

\text{The cost of lithium battery}=\frac{25}{5}

\text{The cost of lithium battery}=5

Therefore, the cost of lithium battery is $5.

Now let us find the sales tax on the cost of helicopter and lithium battery.

\text{Total sales tax}=\frac{6}{100}\times (20+5)

\text{Total sales tax}=0.06\times (25)

\text{Total sales tax}=1.5

Therefore, the total sales tax will be $1.5.

We can find the total cost of helicopter by adding the cost of helicopter, cost of lithium battery and total amount of sales tax.

\text{The total cost of helicopter}=20+5+1.5

\text{The total cost of helicopter}=26.5

Therefore, the total cost of helicopter will be $26.5.

If n is a term of the sequence 14, 8, 2, -4, …, which expression would you give the value of n?
Ipatiy [6.2K]

Answer:

-6n+20

Step-by-step explanation:

The given  term of sequece is  14, 8, 2, -4, …,

Here the first term is 14 and then the terms are decreasing by 6 each time  because 14-8=8-2=...=6

As we know that the nth term of the sequence is given by the formula

t_n=a+(n-1)d\\\text{Substitute the values we get}\\t_n=14+(n-1)(-6)\\t_n=14-6n+6\\t_n=20-6n\\

If n is a term of the given sequence sequence, then its value is -6n+20
