A ratio of pennies to nickels of 2 to 1 means that we can write the number of pennies and nickels in the form   number of pennies = 2x and number of nickels = x   But we know the number of nickels, 10. Hence   x = 10   The total number of coins is given by   2x + x = 3x = 3 × 10 = 30   30nswer : 30
