Susan broke her piggy bank counted 41 coins made up of dimes and nickels. If the
total value of the coin is $3.00, how many dimes and nickels does she have ?

19 dimes, 22 nickels

Step-by-step explanation:

dimes 'd' 10 cents each

nickel 'n' 5 cents each

10d + 5n = 300

n + d = 41

d = 41 - n

10(41 - n) + 5n = 300

410 - 10n + 5n = 300

-5n = -110

n = 22

d = 41 - n = 41 - 22 = 19

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
