A garage sells cars. It offers a discount of 20% off the normal price for cash.

Dave pays £5200 cash for a car.

Calculate the normal price of the car.

6,500

Step-by-step explanation:

Discount = 20%

Therefore the cost price is 100 - 20 = 80%

so,

£5,200 = 80%

To find the 100% ( the cost of the car before the discount), invert the fraction.

100/80 x 5200/1 = 6,500

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
