1. Booker has $1.12 consisting of an equal number of pennies, nickels, and dimes. How many of each kind of coin does he have?
Answer provided by our tutors
let 'y' represent the number of coins of any type (pennies, nickels and dimes)
a penny is 0.01
a nickel is 0.05
a dime is 0.10
1.12 = 0.01x + 0.05x + 0.10x
