Answer:
Amount Simon will have to spend = $4150
Explanation:
Given that:
Rent for summer house = $2000
Discount = 20% = 0.2 
Rent after discount = 2000 - 0.2(2000) = 2000 - 400
Rent after discount = $1600 
Rent of stable per week = $100 
For 8 weeks = 100 * 8 = $800
Hay for 8 weeks = $50 
Fee of riding club = $600 for 4 weeks 
For 8 weeks = 600 * 2 = $1200 
Riding equipment rent = $1000
Discount = 50% = 0.5 
Amount after discount = 1000 - 0.5(1000) = 1000 - 500 
Amount after discount = $500
Total amount = Summer house rent + Stable rent + Hay charges + Riding club fee + Riding equipment rent 
Total amount = 1600 + 800 + 50 + 1200 + 500 = $ 4150
Hence, 
Amount Simon will have to spend = $4150
