The formula for the cost of buying a car is:
Mice21 [21]

Answer:

a) The cost of buying this car is of £6200.

b) The monthly payment is of £450.

Step-by-step explanation:

The cost of buying a car is given by:

cost = 12 X monthly payment + deposit

a) Find the cost of a car when the monthly payment is £350 and the deposit is £2000.

So

cost = 12*350 + 2000 = 4200 + 2000 = 6200

The cost of buying this car is of £6200.

b) The cost of another car is £8000. Find the monthly payment when the deposit is £2600.

Again, the formula is applied. So

cost = 12 X monthly payment + deposit

8000 = 12x + 2600

12x = 5400

x = 5400/12

x = 450

The monthly payment is of £450.

The smiley family had a $62.00 bill and service was great! The tip 20% what is the. Total they paid
Georgia [21]

Answer:

$74.40 cents

Step-by-step explanation:

Given the following question:

20% of 62

In order to find the answer, we use the formula to calculate percentage, then we add that answer onto the bill.

\frac{p\times n}{100}
\frac{20\times62}{100} =20\times62=1240\div100=12.4
=12.4

<u>Now add:</u>
62+12.40=74.40
=74.40

Which means in total after a 20% tip the Smiley family paid "$74.40 cents" for their meal.

Hope this helps.
