Question

Sofia has 25 coins in nickels and dimes in her pocket for a total of $1.65 how many of each type of coin does she have?​ Answers 1. thongdat2 Answer: She has 23 nickels and 5 dimes. Step-by-step explanation: Let n = the number of nickles and d = the number of dimes. The number of each = 28. Set up the equation: n + d = 28 Solve for n: n = 28 – d The total amount is$1.65 or 165 cents:

5n + 10d = 165

Substitute:

5(28 – d) + 10d = 165

140 – 5d + 10d = 165

140 + 5d = 165

5d = 165 – 140

5d = 25

d = 5, the number of dimes.

Solve for n:

n = 28 – d

n = 28 – 5 = 23, the number of nickles.

Proof:

5n + 10d = 165

5(23) + 10(5) = 165

115 + 50 = 165

165 = 165
