I NEED HELP I will give brainliest.

C

x = Grace's collection

3x = Maci's collection

4 = Kendra's collection

52 = Total collection

Because the total is 52, the equation would be x + 3x + 4 = 52. Add the like terms to get 4x+4=52. Subtract 4 on both sides to get 4x=48. Divide 4 on both sides to get x = 12. Because Maci's collection is 3x, she should have 36 earrings.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

it is true
