Step-by-step explanation:

Here we have , Bruce saved $ 35.00 to buy a new video game. The game's original price was $ 42.00 , but it was on sale for 30% off. The sales tax rate was 5%.  We need to find Did Bruce have enough money to buy the game .Let's find out:

We have , Bruce saved $ 35.00 to buy a new video game . The game's original price was $ 42.00 , but it was on sale for 30% off. i.e.

Price = $Original price - \frac{Original-price(30)}{100}$

⇒ $42-\frac{42(30)}{100}$

⇒ $42-\frac{1260}{100}$

⇒ $42-12.6$

⇒ $29.4$

Now,  The sales tax rate was 5%. So , total amount to be paid is :

⇒ $29.4 + \frac{29.4(5)}{100}$

⇒ $29.40 +1.47$

⇒ $30.87$

Bruce have $35 which is greater than amount to be paid i.e. $30.87 . So , Bruce have enough money to buy the game .
