The bike you have been saving for is discounted 20%. You have $400 saved to purchase it. The retail price of the bike is $450. There is a 5.25% sales tax added to the price of the bike.

You cannot buy it.

Step-by-step explanation:

$450 with a 20% percent discount would be $360

Add in a sales tax of 5.25%, and it amounts to $549 in total.

Since you only have $400, you cannot buy the bike.

yes 378.90

Step-by-step explanation:360 when u remove the 20 percent plus the tax is 378.90

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
