A change purse contains an equal number of pennies, nickels, and dimes. The total value of thecoins is 160 cents. How many coins of each type does the purse contain?Number of pennies :

Answer 1

10 pennies

1) Considering that:

1 penny = 1 cent

1 nickel = 5 cents

1 dime= 10 cents

2) We can write out the following equation relating all that:

`\begin{gathered} 1c+5c+10c=160 \\ 16c=160 \\ (16c)/(16)=(160)/(16) \\ c=10 \end{gathered}`

Note that we wrote 'c" for coins:

3) Thus we can write the following as our answer picking the number of pennies as 1c

1c = 1 * 10 = 10 pennies
