Answer:
He may have 1 penny, 2 dimes, and 3 nickels.
Step-by-step explanation:
"Luis has some dimes, nickels and pennies."
He has to have at least one coin of each.
"and the fewest pennies,"
The smallest number of pennies he can have is 1.
1 penny is worth $0.01.
"If Luis has more nickels than dimes,"
He has more nickels than dimes, but pennies is the least, so he must have at least 2 dimes.
2 dimes are worth $0.20.
Since he has more nickels than dimes, he has to have at least 3 nickels.
3 nickels are worth $0.15.
Total $0.01 + $0.20 + $0.15 = $0.36
The smallest amount of money he can have is $0.36, which is less tan $20.
He may have 1 penny, 2 dimes, and 3 nickels.
