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 - (Original-price(30))/(100)`

⇒
`42-(42(30))/(100)`

⇒
`42-(1260)/(100)`

⇒
`42-12.6`

⇒
`29.4`

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

⇒
`29.4 + (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 .
