I need helpppppppppp please

Answer 1

30

Explanation:

The original amount of cars is represented by 100%

Divide the cars sold by 70 to find 1% then multiply by 100 to calculate the number of cars the dealer had for sale, that is

number of cars =
`(21)/(70)` × 100 = 30

Answer 2

answer: 21 is 70% of 30

Working out percentages

We have, 70% × x = 21 or, 70100 × x = 21

Multiplying both sides by 100 and dividing both sides by 70,

we have x = 21 × 100 70 x = 30

If you are using a calculator, simply enter 21×100÷70, which will give you the answer.
