Write a system of equations to describe the problem situation. It is not necessary to solve the problem. Martina has 58 nickels and dimes. She has $3.10 altogether. She has x nickels and y dimes.
A) y = 58 - x, 0.05x + 0.10y = 3.10
B) x + y = 58, 0.05y + 0.10x = 3.10
C) x + y = 58, 0.25y + 0.10y = 3.10
D) x - y = 58, 0.05x + 0.10y = 3.10
E) x – y = 58, 0.05y + 0.25x = 3.10
A) y = 58 - x, 0.05x + 0.10y = 3.10
