steve had P2.50 in 10c-coins in the pocket of his jacket He discovered he had a small hole in his pocket and two 10c-coins dropped through that small hole every 5 minutes How much money did Steve have then after walking for half an hour

Sagot :

30 minutes ÷ 5 minutes = 6 (the number of times that every 2 pieces of 10 centavo   coin is dropped)

Let N be the money left after walking for 30 minutes (half an hour)

N = 2.50 - 6(2 × 0.10)
N = 2.50 - 6 ( 0.20)
N = 2.50 -  1.20
N =  1.30 pesos
