Question

diego is collecting dimes and nickels for penny war he has collected $22.25 this represented by the equations 0.10x + 0.05y =22.25 select all the values that could be solutions

Answer 1

One solution is x = 1 and y = 443 because

0.10(1) + 0.05(443) = 22.25.

So, (1, 443) is a solution.

Since, 1 dime = 2 nickels,

Increment of 1 in x-value = Decrease of 2 in y-value.

Therefore, the set of possible solutions are {(1, 443), (2, 441), (3, 439), (4, 437),......(222, 1)}
