Solution:
In a parking lot there are tricycles and bicycles. There are 60 vehicles, namely bicycles and rickshaws, and many wheels 145. Bicycle parking costs Rp.300 and Rp500 rickshaws. Then the parking lot's income is ...
vehicles = 60
Wheels = 145
bicycles = B
rickshaws = 60 - B
Wheels = 2 * B + 3(60 - B)
=180 - B
180 - B = 145
=> B = 35
bicycles = 35
rickshaws = 60 - 35 = 25
Bicycle parking costs
Bicycle Rp.300
rickshaws 500
parking lot's income = 35 * 300 + 25 * 500
=10500 + 12500
= 23000
________________________________________
kendaraan = 60
Roda = 145
sepeda = B
becak = 60 - B
Roda = 2 * B + 3 (60 - B)
= 180 - B
180 - B = 145
=> B = 35
sepeda = 35
becak = 60 - 35 = 25
Biaya parkir sepeda
Sepeda Rp.300
becak 500
Penghasilan parkir = 35 * 300 + 25 * 500
= 10500 + 12500
= 23000 Rp
