Answer 1

113.15 pounds

Explanation:

Radha claims 43p per mile * 341 miles = 43p/mile * 341 miles = 14663p = 146.63 pounds from her employer

Next, we can calculate the amount she pays.

55 miles = 1 gallon

1 gallon/55 miles = 1 (note miles are on the bottom so it crosses out)

341 miles * 1 = 341 miles = 341 miles * 1 gallon/55 miles = 6.2 gallons

1 gallon = £5.40

£5.40/1 gallon = 1 (note gallon is on the bottom so it crosses out)

6.2 gallons * 1 = 6.2 gallons * £5.40/1 gallon = £33.48

how much more she claims than she pays = amount she claims - amount she pays = 146.63 - 33.48 = 113.15 pounds
