1. Change 15% to a decimal: 0.15. 2. Multiply the decimal by the bill: 0.15 x 14.40. 3. This gives 2.16, so the tip should be $2.16. 4. $1.44 is a 10% tip and $2.88 is a 20% tip, so neither matches the 15% asked for. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 6 "Percents", section 6.2 Solve General Applications of Percent_

1. Change 12% to a decimal: 0.12. 2. Multiply the decimal by the paycheck: 0.12 x 2,165. 3. This gives 259.80, so $259.80 went into savings. 4. $216.50 is only 10% of the paycheck, the slip that comes from moving the decimal point without using the actual rate. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 6 "Percents", section 6.2 Solve General Applications of Percent_

1. The rent is the part and the monthly pay is the whole. 2. Divide the part by the whole: 750 divided by 3,000. 3. This gives 0.25. 4. Move the decimal point two places to the right and add a percent sign: 25%. 5. 30% would be $900 of rent and 20% would be $600, so both fail a quick check against the actual $750. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 6 "Percents", section 6.2 Solve General Applications of Percent_
