Lisa buys a television for $4185. if the sales tax is $292.95. what percent is sales tax?

Romashka-Z-Leto [24]

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%.

The Oliver Company plans to market a new product. Based on its market studies, Oliver estimates that it can sell up to 5,500 uni

Ghella [55]

For the Oliver Company to break even, the total revenue must equal the sum of the variable costs and the fixed cost. Mathematically, this can be represented as: Total revenue = 0.4*(Total revenue) + (Fixed Costs) Let the number of units sold be x. then, 7*x = 0.4*(7*x) + 6300 Thus, x = 6300/(0.6*7) = 1500 units. Thus the company will have to sell 1500 units to break even.
