    Answer:

    Sales tax = 7%.

    Step-by-step explanation:

    Let x be the percent of sales tax.

    We have been given that Lisa buys a television for $4185. The sales tax is $292.95.

    We need to figure out x such that x percent of 4185 equals to 292.95. Let us represent this information in an equation.

    \frac{x}{100}*4185=292.95

    Let us multiply both sides of equation by 100.

    100*\frac{x}{100}*4185=100*292.95

    x*4185=29295

    x=\frac{29295}{4185}

    x=7

    Therefore, sales tax is 7%.

    Let us cross check our answer by calculating 7% of 4185.

    7\%\text{ of } 4185=\frac{7}{100}\times 4185

    7\%\text{ of } 4185=0.07\times 4185

    7\%\text{ of } 4185=292.95

    We can see that 7% of 4185 is 292.95. Hence, sales tax is 7%.
