The cost of a ticket increases by 10% to £18.15. Work out the original cost

Denote the original cost: x

The cost of a ticket increases by 10% to £18.15, then:

x*(1 + 10%) = 18.15

=> x*(1 + 10/100) = 18.15

=> x*(110/100) = 18.15

=> x = 18.15*(100/110) = 16.5£

Hope this helps!

step-by-step explanation:

just took the test

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
