Question

Michelle has $14 in purse in 5cent 10cent and 20cent coins. If she has an equal number of each coin type, how many coins does she have in her purse

Answer 1

There would be 40 20cent coins, 40 10cent coins, and 40 5cent coins.

Answer 2

She have 40 coins in her purse

Explanation:

1 dollar = 100 cents

14 dollar = 1400 cents

We are given that she has an equal number of each coin type

Let x be the no. of coins

Value of x coins of 5 cents = 5x

Value of x coins of 10 cents = 10x

Value of x coins of 20 cents = 20x

So,
`5x+10x+20x=1400`

`35x=1400`

`x=(1400)/(35)`

`x=40`

Hence she have 40 coins in her purse
