Please help fast!! Katrina has $3.60 worth of nickels and dimes. She has 46 coins in total. How many nickels and dimes does she
Igoryamba

Answer:

20 nickels and 26 dimes

Step-by-step explanation:

  • She has $3.60 in nickels and dimes
  • a nickel is $0.05 and a dime is $0.10
  • let n be the number of nickels and d be the number of dimes
  • thus the first equation is 3.6 = 0.05n +0.1d
  • If she has 46 coins then n + d = 46
  • then n = 46 - d
  • sub n = 46 - d into 3.6 = 0.05n +0.1d
  • 3.6 = 0.05(46 - d) + 0.1d
  • 3.6 = 2.3 -0.05d+0.1d
  • 1.3 = 0.05d
  • 26 = d
  • sub d = 26 into n+d=46
  • n+26=46
  • n=20
  • Check by subbing n=20 and d=26 into 0.05n +0.1d
  • 0.05(20) +0.1(26)
  • 1+2.6 = 3.6
