Kyle runs a gardening company and sometimes needs to hire additional machinery and tools. For his latest job Kyle hired a chipper to help clear an overgrown piece of land.
The cost per day was
- £24.50 for the first 5 days
- reduced by 20% for day 6
- the same as day 6 for day 7 onwards.
The total cost was £259.70
For how many days did Kyle hire the chipper?
Answer:
First minus the cost of the first 5 days by doing 259.70 – 122.5 = £137.20
The cost per day after 5 days is 24.5 x 0.8 which equals £19.60
To find the number of days after the fifth divide 137.20 by 19.60 to get 7 days
Therefore, the chipper was hired for 12 days.
