Question

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

Answer 1

Answer:

B is the answer

Step-by-step explanation:

Dime + nickel = 22

i.e. d+n = 22

now values of dime + nickel = 1.90$

i.e. 0.1d + 0.05n = 1.90$
