Bri buys bracelets for $2 and marks up the bracelets 170%. How much does Bri charge per bracelet?
Answer explanation
Bri buys the bracelets for $2 and then marks up the price by 170%. To calculate the selling price, we need to add the markup to the cost price. The markup is 170% of $2, which is $3.40. Therefore, Bri charges $3.40 per bracelet.

The county fair anticipates visitors numbering 456,000 with a percent error of 4.5%. What is the range of visitors to the fair?
Answer explanation
The range of visitors to the fair is calculated by adding and subtracting the percent error from the anticipated number of visitors. 4.5% of 456,000 is 20,520. Therefore, the range of visitors is from 456,000 - 20,520 (435,480) to 456,000 + 20,520 (476,520). This matches the given option.

Brooke is getting a manicure and wants to leave a 24% tip. Write an equation Brooke can use to calculate the tip y if the bill is x dollars.
Answer explanation
The question asks for an equation to calculate a 24% tip on a bill. The correct option 'y = .24x' represents this. Here, 'y' is the tip amount and 'x' is the total bill. By multiplying the total bill 'x' by .24, Brooke can find out the tip amount 'y'. This equation correctly represents the relationship between the bill and the tip.

DJ is having a birthday party at the ice skating rink. He wants to tip the host 18% before tax. The sales tax is 7.5%. Write an equation to determine the total cost DJ will pay for the party, y, given the amount of the bill before tax & gratuity, x.
Answer explanation
The equation y = .18x + .075x represents the total cost DJ will pay for the party. Here, 'x' is the amount of the bill before tax and gratuity. The term .18x represents the 18% tip DJ wants to give to the host, and .075x represents the 7.5% sales tax. Adding these two gives the total cost 'y' DJ will pay.
