a.) 50 – 5x = y and 46 – 4x = y
b.) 5x + 50 = y and 4x + 46 = y
c.) 5x – 50 = y and 4x – 46 = y
d.) 5 – 50x = y and 4 – 46x = y

Answer 1

a

Explanation:

Let's look at Enrique:

He starts with $50 and every time he buys lunch his account goes down by 5. The y would represent how much money he has left in his account.

So, say he buys 3 lunches how much is in his account if he started with 50?

50 - 5-5-5 = 35

Use the equation

50 - 5(3) = y

50 - 15 = y

35 = y
