Anna has four more nickels than dimes in her pocket for a totalof $1.25. Which equation could be used to determine the numberof dimes, x, in her pocket?A$0.05(x + 4) + $0.10x = $1.25B $0.05(4x) + $0.10x + $1.25C$0.05x + $0.10(x + 4) = $1.25D$0.05x + $0.10(4x) = $1.251 point

Sagot :

Let 'x' be the amount of nickels Anna has, and 'y' the amount of dimes.

If she has '4 more nickels than dimes' this is:

[tex]y=x+4[/tex]

And the total amount is $1.25, that can be written as:

[tex]0.05\cdot x+0.10\cdot y=1.25[/tex]

If we replace the equivalence between y and x here we get:

[tex]0.05x+0.10(x+4)=1.25[/tex]

The correct answer is option C
