Answer:
She have 40 coins in her purse
Step-by-step 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, [tex]5x+10x+20x=1400[/tex]
[tex]35x=1400[/tex]
[tex]x=\frac{1400}{35}[/tex]
[tex]x=40[/tex]
Hence she have 40 coins in her purse
