Kiley found $8.75 in nickels and quarters in the cabinet above the washing machine. Let x represent the number of nickels

she found and y represent the number of quarters. Which equation written in standard form represents the amount of

money she found, and what does its y-intercept represent?

O The equation in standard form is 0.05x + 0.25y = 8.75; the y-intercept represents that if she found 0 nickels, she must

have found 175 quarters.

The equation in standard form is 0.05x + 0.25y = 8.75; the y-intercept represents that if she found 0 nickels, she must

have found 35 quarters.

The equation in standard form is x + 5y = 175; the y-intercept represents that if she found 0 nickels, she must have found

175 quarters.

The equation in standard form is x + 5y = 175; the y-intercept represents that if she found 0 nickels, she must have found

35 quarters.

0.05x+0.25y=8.75; the y intercept represents that if she found 0 nickels she must have found 35 quarters.

Step-by-step explanation:

1. Solve for y:

0.25y = 8.75-0.05x (subtract 0.05x on both sides)

y = (8.75-0.05x) / 0.25 (divide by 0.25 on both sides)

2. Since the y intercept can be found when x equals 0, plug in 0 for x into the equation.

y = (8.75-0.05 (0)) / 0.25

y = 8.75/0.25

y=35
