An item costs $440 before tax, and the sales tax is $35.20. Find the sales tax rate. Write it as a percentage.

To find the sales tax rate, we can divide the amount of sales tax by the cost before tax.

Sales tax rate = (sales tax / cost before tax) * 100%

Sales tax rate = (35.20 / 440) * 100%

Sales tax rate = 0.08 * 100%

Sales tax rate = 8%

Therefore, the sales tax rate is 8%.

The next model of a sports car will cost 3.9% more than the current model. The current model costs $38,000. How much will the price increase in dollars? What will be the price of the next model?

To find the price increase in dollars, we can multiply the current price by the percentage increase.

Price increase in dollars = current price * percentage increase

Price increase in dollars = $38,000 * 3.9%

To find the price of the next model, we can add the price increase to the current price.

Price of next model = current price + price increase in dollars

Price of next model = $38,000 + (3.9% * $38,000)

To calculate this, we need to convert the percentage to decimal form: 3.9% = 0.039

Price increase in dollars = $38,000 * 0.039 = $1,482

Price of next model = $38,000 + $1,482 = $39,482

Therefore, the price increase in dollars is $1,482 and the price of the next model will be $39,482.

(a) What percent of 51 is 127.5?

b) 25.83 is 52.5% of what number?

(a) To find what percent of 51 is 127.5, we can divide 127.5 by 51 and then multiply by 100 to convert it to a percentage.

Percent = (127.5 / 51) * 100

Percent = 250
