The price of a holiday was decreased by 12% to £600. What was the price before the decrease? Give your answer to the nearest pen

s2008m [1.1K]

Answer: £5000

Step-by-step explanation:

If 12% decrease = £600

Then (100- 12)% = x

100% = x

0.12x = 600 x 0.88

0.12x = 528

Divide both sides by 0.12

£4400

Therefore, original price before 12% decrease was £5000

bazaltina [42]

Answer:

523.6 km

Step-by-step explanation:

Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...

time = distance/speed

Then the total travel time in hours is ...

x/160 +(1020-x)/105 = 8

21x +32640 -32x = 26880 . . . . . multiply by 3360

5760 = 11x . . . . . . . . . add 11x -26880

523.6 ≈ x . . . . . . . . . . divide by 11

Aidan traveled about 523.6 km by train.
