Question

The total amount Y​ (in dollars) in your savings account after buying x​ video games is represented by y=70−10x​ . You have $40 in your account after buying video games. How many video games did you buy?

Answer 1

330

Explanation:

substitute x for 40 because that is how much you have in your account.

y= 70 - 10(40)

y = 70 - 400

y = 330

Therefore you bought 330 video games!!
