A total of 22 dimes and nickels have a value of $1.90. If d represents the number of dimes and n represents the number of nickels, which system of equations models this situation? A.

d + n = 1.9
0.1d + 0.05n = 22

B.

d + n = 22
0.1d + 0.05n = 1.9

C.

d + n = 1.9
0.1d + 0.5n = 22

D.

d + n = 22
0.1d + 0.5n = 1.9

d + n = 22 and 0.1 d + 0.05n = 1.9 Step-by-step explanation: Let d be the number of dimes and n the number of nickels. Total dimes = 22 Therefore, d + n = 22 1 dime = 10 cents = 0.1 1 nickel = 5 cents = 0.05 Value of 22 dimes = $ 1.90 So , 0.1d + 0.05n = 1.9 Therefore, d + n 22 and 0.1d + 0.05n = 1.9 models the given% D% 3D situation.
