Days: 10, 20, 30, 40

Hay (Ib): 250, 500, 750, 1000
Complete the question to show the relationship between the number of days, z and the amount of hay a cow eats y
__=__ __

y = (25 * z) + 225

25 y or 25 x

25d.

That’s not what I asked

Apologies for the confusion. The correct equation to show the relationship between the number of days (d) and the amount of hay a cow eats (y) would be:

y = 25d + 225

25 y or 25 x, you have to pick one of THESE answers. None of that 25d

25y

Wrong, it was 25x

Apologies for the misunderstanding. The correct equation to show the relationship between the number of days (x) and the amount of hay a cow eats (y) would be:

y = 25x

At this rate, how much will a cow eat over 90 days?
