Equation is 145 - 45 x = 10.
Billy bought 3 video games.
Step-by-step explanation:
As given,
Total Balance in the gift card = $145
The cost of each video game = $45
After purchasing , Balance in Gift card = $10
Now,
Let Total number of video games Billy purchase = x
⇒Cost for video game = 45x
Now,
As we know ,
Total Balance - Purchased Item = Balance left
⇒ 145 - 45 x = 10
∴ The equation is 145 - 45 x = 10
Now,
145 - 10 = 45x
⇒135 = 45x
⇒ x =
= 3
∴ we get
Billy bought 3 video games
