Kyla has 20 more 10-cent coins as he does 5-cent coins. He has half as many 1-peso coins than 10-cent coins. If he has a total of 38 pesos how many 5-cent coins does he have?

Answer 1

number of 5-cent coins ---- x

"Kyla has 20 more 10-cent coins as he does 5-cent coins"
-----> just translate that:
number of 10-cent coins = x+20

"He has half as many 1-peso coins than 10-cent coins"
---> number of 1-cent coins = (1/2)(x+20)

How many does he have in total ?
